The patch is okay, but can you please bug the newlib guys about upgrading to 2.62?

Will address, but let's sort out the stuff mentioned below first.


Since they are already using 2.61, it's okay that they do not use override.m4 which would give an error (my patch to use it was ignored on the newlib mailing list); but they should upgrade to 2.62 in order to fix PR35457.

Hmm. I didn't know they were using an updated Autoconf already. I kind of like the override.m4 approach, and think that it can be useful even when GCC and binutils have moved.

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.

Kai is waiting for this one to go in, in order to define
AC_TYPE_INTPTR_T in override.m4.

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.
