What is the minimum version of GCC required to build PHP?

 I am asking because using GCC 2.95.3 and GCC 3.4.0 I get errors related
 to the usage of intptr_t (see http://pastebin.com/9Gn0AAXA).

 Over in Room 11, Michael just pointed out that this could be related
 to php_stdint.h.

Yes, we could probably just add a check whether intptr_t is defined and if not do so according to the bit width of the platform.

I remember some bugs affecting php with 2.95.x, I would be careful before
using it. We may as well ask for 3.x with 7+, we may have discussed that
for 5.5 or 5.6, if I am not mistaken.

 Okay, this does not seem to be related to the GCC version but rather
 to the fact that some int types etc. are not defined on/for my platform.
 If I use -Dintptr_t=long -Duintptr_t=ulong, for instance, then I can
 compile PHP (but not link it, but that's another issue).
