Bug#637418: gnat-4.6 ftbfs with eglibc-2.13-16

[Matthias Klose <doko@debian.org>]

Package: gnat-4.6
Version: 4.6.1-3
Severity: serious

On i386:

linux-libc-dev: /usr/include/i386-linux-gnu/asm/posix_types_32.h

the build fails on both sid and oneiric.  It goes away when not using -I-,
however I'm unsure why it did succeed to build earlier in sid.
