I tried compiling the new test release at http://alpha.gnu.org/gnu/grep/grep-2.5.4-20080209b.tar.gz with gcc 4.2.3 on CentOS 5. configure gave this warning:
config.status: WARNING: intl/Makefile.in seems to ignore the --datarootdir setting ... which is because gettext has apparently not been updated in a long time. I suggest using the latest official releases of gettext, automake, and autoconf. Best, karl
