Well, that's a lie. When they say "india", they mean the subcontinent. That seems to be the basis of your references. Prove to me they mean modern India, and not Ancient India in your previous references. You won't be able to..
Look, its quite obvious that "India" refers to modern India unless specified otherwise. No author would be **** enough to confuse modern India with Pakistan.
If a reference is made to ancient India, it is usually written as "now in Pakistan" or something of the sort.
Hindu is an assumption, based on the name, which in turn is a common Hunnic derivation for invaders that came to Pakistan. They include Vedic people, and I believe Buddhist people in this category. Remember in 600 AD, Pakistan was not a Hindu dominanted country. Therefore it is likely that Brahmagupta was a Vedic or Buddhist follower.
It is obviously not an assumption. You can't simply call anything you disagree with an assumption. I have given plenty of sources describing him as a hindu. By your standards, this fact is verified.
There was no Vedic religion in 600 AD, which was the era of classical hinduism. The conclusion that he was a hindu is based upon his work, which clearly gives away his hindu beliefs.
The Chinese pilgrim Hiuen Tsang visited Multan in 641 AD, and described Multan as a grand city whose people did not believe in Buddha. He said the city had eight deva temples and one grand temple dedicated to Surya dev.

History ..: Hamara Multan :..
In any case, the Vedic religion itself is an early form of Hinduism.
My link clearly says born in Multan. So which is it? It is clear that he had connections with Multan though.
It says he was "of Multan". If you notice, in 600 AD, Mulan was under hindu rule. The people there were not buddhists but Sun worshippers (i.e. Surya Dev).
Before the Arab conquests, Multan was ruled by a Brahmin king Raja Chach.
Multan was mostly ruled by hindu kings till the invasion of the Arabs.
Out of all these links, only one of them has said where he was born..this too from google book search. Alright, here is another google book search..
A History of Sanskrit Literature - Google Book Search
Says Brahmagupta was born AD 598, son of Jisnu of Bhillamalla, near Multan etc.
Bhillamala refers to modern Bhinmal, on the border of Gujarat and Rajasthan. I don't see how this link helps your case. It clearly mentions him as born within the boundaries of India.
None of your links except one, says where he was born. I posted a solid link to say he was born in Multan plus one of the many google.books references. My link, Strasbourg University, is a highly credible academic link.
My links say he was "from Bhillamala". Clearly, by your definition, that means that he was born in Bhillamala since even your link says that he was "of Multan".
On top of that, I have given you links that use the word "born" in conjunction with "Bhillamala".
Read the following paragraph:
The famous Iranic scholar Al-Beruni summarised these canons thus, providing slightly different names for the various systems:
"They [the Indians] have 5 Siddhāntas:
1. Sūrya-Siddhānta, ie. the Siddhānta of the Sun, composed by Lāṭa,
2. Vasishṭa-siddhānta, so called from one of the stars of the Great Bear, composed by Vishnucandra,
3. Pulisa-siddhānta, so called from Paulisa, the Greek, from the city of Saintra, which I suppose to be Alexandria, composed by Pulisa.
4. Romaka-siddhānta, so called from the Rūm, ie. the subjects of the Roman Empire, composed by Śrīsheṇa.
5. Brahma-siddhānta, so called from Brahman, composed by Brahmagupta, son of Jishṇu, from the town of Bhillamāla between Multān and Anhilwāra, 16 yojanas from the latter place.

Read point number 5. It quotes directly from Al-Beruni. I hope you don't say that this might be a mistranslation or that this link is not credible, because I really don't think someone can mistranslate something this badly.
I think it is now beyond doubt that he was born in Bhillamala,
between Multan and Anhilwara
He was an ancient Pakistani working in the region of modern Northwest India (Rajasthan). Whether he made all his discoveries in India or only some is not known. What is known is that he was born in Multan (son of Jisnu).
Here is a quote that ought to seal the case:
"his book Brahma-sputa-siddhanta describes him as the teacher from Bhillamala, which is a town now known as Bhinmal"
Source:
http://books.google.com/books?id=yPsl0WzBzZYC&pg=PA80&dq=%22brahmagupta%22+%22bhillamala%22&lr=&ei=g7V9R7XuH4KmtgPSlanFBA&ie=ISO-8859-1&sig=eHBZ10YC4as67TJVxLHtbHhMpvs#PPA79,M1
his own work Brahma-sputa-siddhanta describes him as born in Bhinmal. What more proof do you need?
If you need more proof, here is a german professor:
Entwicklung der Darstellung und Dokumentation von algebraischen Sachverhalten
It says that he worked at the astronomical observatory at Ujjain. So there goes your assumption that he didn't do any of his work in India.
Here is another source:
Brahmagupta: 598 A.D. - ). The son of Jisnu, was the author of Brahma-Siddhanta (828 A.D.) or Sphuta-Siddhanta. He did not accept the diurnal rotation of the earth. Alberuni says that he was a native of Bhillamala near Multan. Probably, he lived in the court of Chapa king, Vyagra - mukha. Perhaps, he is the first to use algebra for astronomical calculations and to give zero its rightful positions.
http://www.new.dli.ernet.in/data/upload/0047/997/TXT/00000020.txt
It says, that Al-Beruni described him as a native of Bhillamala. This corresponds with my earlier link quoting Al-Beruni.
So, it is clear now that he was born in Bhillamala (bhinmal), headed the observatory at Ujjain, and wrote his Brahma-sputa-siddhanta at Bhinmal.
Here is yet another quote in portuguese:
Matemático da Índia Central nascido em Ujain, que demonstrou a solução geral para a equação do segundo grau em números inteiros, as diofantinas, e desenvolveu a métodos algébricos gerais para aplicação na astronomia, em sua principal obra Brahmasphutasiddhanta (628), um trabalho matemático escrito em 25 capítulos, em Bhillamala, onde era professor e que hoje é a cidade de Bhinmal, então capital das terras regidas pela Dinastia de Gurjara
Brahmagupta
It says that he wrote Brahmasphutasiddhanta at Bhillamala, which is modern Bhinmal, and the capital of the dynasty of Gurjara.
