Me too, however, newlib also does not use the toplevel config/ directory 
so for now it's not a problem because they won't get the goodies -- but 
neither will they get the problematic parts, i.e. the 
_GCC_AUTOCONF_VERSION check.

I expect that after moving to Autoconf 2.6x, we can be less strict and 
just mandate the last released version of Autoconf, so the 
_GCC_AUTOCONF_VERSION stuff will go away.  So, patch is okay, and the 
newlib guys can keep their current aclocal configuration.

The m4wrap patch is okay too.

Kai could use the already-there macro to create a stdint.h-like file. 
It's already used by libdecnumber and libgfortran, among others.
