[PATCH] Fix minor AIX compilation warning in libiberty.

- Subject: [PATCH] Fix minor AIX compilation warning in libiberty.
This trivial patch fixes a compilation warning when compiling libiberty
on AIX using GCC. The "#pragma alloca" is only required on AIX when
using IBM's compilers. The patch below changes the "#if" around the
#pragma in regex.c to match the one in putenv.c. These are the only
two uses of "#pragma alloca" in libiberty.
Tested by bootstrapping GCC on i686-pc-linux-gnu and both with and
without xlC on powerpc-ibm-aix5.1.0.0.
Ok for mainline (or somewhere else)?

* regex.c: Only use "#pragma alloca" on AIX when not using gcc.
