Patch for GNU grep to allow compilation on FreeBSD

[Tim Robbins]

Hi,

This patch is required for GNU grep 2.5 to build on FreeBSD 5.0-CURRENT;
I assume it is also required for everything after and including
4.4-RELEASE.

The problem is that FreeBSD's strerror_r() returns int (as required by
IEEE Std. 1003.1-2001), not char * like glibc.
