Old glibc vs. gcc-4.3

Per http://lists.debian.org/debian-68k/2008/04/msg00033.html

The glibc support for the C99 inline semantics was added in glibc 2.6 and all the non-TLS support was removed. GCC 4.3 and later use C99 inline semantics in -std=gnu99 mode.

Compiler status

• We don't have an Ada or D compiler at the moment since both compilers require special bootstrapping which has never been done. Michael Casadevall has been been able to build the Ada cross-compiler, but hasn't successfully bootstrapped the native compiler
• D will probably require similar work done for it.
