Something seems wrong here and it's not my version of Autotools. When I download a fresh copy of M4 1.4.17, I am able to install it with GCC and Intel without any trouble. The only problems I was having were with PGI. But with the proposed patch, I am now unable to install M4 with GCC, Intel, or PGI. Regardless of which compiler I use, I still get the message about aclocal-1.14 being missing on my system. Any idea why the patch would cause this problem?
