I think the key thing is that Git has very few external dependencies. You'll note that I had to turn off OpenSSL support to get it to compile. The only other library from back then is libz, which is extremely stable.

Other than, it just depends on a reasonable C compiler and a POSIX libc, both of which have been standardized for decades.

I suspect that today's Git will also compile pretty well in 15 years, but you'll probably to say NO_GETTEXT and turn a few other knobs. Libcurl might eventually be a problem, though I've been pretty impressed with its stability and backwards-compatibility so far (and of course it's optional if disabling http support is OK).
