Modifying an m4 file on a mac, something as simple as a changing the copyright year makes the common/autoconf/autogen.sh to fail making configure to fail completely.

Here is my output from an email thread:
==

$ bash common/autoconf/autogen.sh
Generating generated-configure.sh
/usr/bin/gm4:stdin:185: bad expression in eval: 32 > <dynamic>
autom4te: /usr/bin/gm4 failed with exit status: 1
Generating custom generated-configure.sh
/usr/bin/gm4:stdin:185: bad expression in eval: 32 > <dynamic>
autom4te: /usr/bin/gm4 failed with exit status: 1
$


Also, as a proof of concept, all I changed was the copyright year from 2013 to 2014 in the comments and it fails.

$ hg diff autoconf/custom-hook.m4
diff --git a/autoconf/custom-hook.m4 b/autoconf/custom-hook.m4
