5.0.1: phpize produces errors

[Gerry Reno]

I am trying to run phpize in the gmp-5.0.1/ directory extracted from the 
5.0.1 tarball.  It is giving me this error:

  gmp-5.0.1]# $PHPIZE
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
/usr/bin/m4:configure.in:75: recursion limit of 1024 exceeded, use -L<N> 
to change it
autom4te: /usr/bin/m4 failed with exit status: 1

m4 appears to be infinitely recursing.  Even if I add -L64000 to the M4 
macro it still errors.

I don't know what is causing this problem but I've been able to build 
other phpized extensions successfully.
