My understanding is that the GCC4 ABI is some kind of industry
standard API that should be the same for all current C++ compilers.
Back in the bad old days, a compiler vendor either defined their own
ABI, or they used the same ABI as that of the dominant vendor.
At some point all the compiler vendors got together to define a common
ABI for each instruction set architecture.
The reason we need different Haiku builds for GCC 2.95 and GCC 4 is
that 2.95 was from before that common ABI was defined.
I don't have a link for you; it's something I read about in a trade
magazine several years ago.
