configure m4 problem

[Ozkan Sezer]

Hi:

Our mingw-w64 (mingw-w64.sf.net) runs automated builds
using buildbot. Buildbot runs on python and our builders
report failures during gmp builds which is related to this
old issue:
http://article.gmane.org/gmane.comp.lib.gmp.bugs/2114/

We would very much like this be solved. Any of the three
solutions suggested in the mail linked above would be OK.

Regards.
