Pursuant to Arno's comments on PR ada/49444, here is another patch that
allows GCC to compile with Ada support on Debian GNU/kFreeBSD.
2011-08-04 Ludovic Brenta <ludo...@ludovic-brenta.org>
* gcc/ada/gcc-interface/Makefile.in (kfreebsd%):
- use s-taprop-posix.ad[bs] instead of s-taprop-linux.ad[bs]
- use use s-tasinf.ad[bs] instead of s-tasinf-linux.ad[bs].
* s-osinte-kfreebsd-gnu.ads: allow the above by bringing the
interface closer to s-osinte-freebsd.ads.
