Compiling re2c with gcc 2.95

[Mark <ad...@asarian-host.net>]

Has anyone been able to compile re2c with a gcc 2.95 compiler? I have a

gcc43 also, but Perl was compiled with 2.95, so the Rule2XSBody stuff

needs to be compiled with 2.95, too, right? Now I get this weird error:

Thanks! This is good to know. :) I went by the 'sa-compile' info for
Rule2XSBody, which said:

"This requires re2c (see http://re2c.org/), and the C compiler used to
build Perl XS modules, be installed."

So, I'm gonna give this a try then (should things core-dump, I'll find
out soon enough).

Not really, no. The C ABI doesn't change much (or at all), certainly not
on platforms that anybody actually uses. Breaking the C ABI torpedoes
everyone on that platform, so it changes very rarely indeed. GCC
generally does it only when a bug is found in its compatibility with the
native compiler, and FreeBSD's native compiler *is* GCC, so it should
never change at all (modulo bugs).

Even the C++ ABI is very nearly stable now.
