Compiling gettext on some systems (0.15 as well as 0.16 did it for me, it probably goes back further) seems to fail for some people, giving a "undefined reference to `ceil'" error. This error is discussed on on the bug-gnu-utils mailing list as well as here.

I worked around the problem by editing config.status and setting MSGMERGE_LIBM to "-lm", but Bruno later offered a less hackish solution: (diff follows)
2007-01-10 Bruno Haible <brunoØclisp.org>
* configure.ac (MSGMERGE_LIBM): Avoid inlining of the ceil, sqrt calls
on glibc systems.
Reported by I. Thomas Cundiff <tcundiffØeclipse.net>.

Hope it helps. Good luck.
