As I wrote some weeks ago, I'd like to drop the gcc-3.1.1 support since 3.2.1 seems to work at least as well (and much better on some systems).

Dropping gcc-3.1.1 currently just means removing the diff file, but it makes it easier to maintain whenever there are changes in the diff (and I suppose there'll be some when the debug info problems will be fixed).

So, that's your last chance to raise any objections.

"Objection" would be a too big word, but I do use "gcc-3.1.1.diff".

I use it to build gpc with a Apple gcc (apart from the build with FSF gcc-3.2.1).

There are two reasons to do so:

(1) find out how stable it is, as compared to the build with mainline gcc-3.2.1 (2) being able to use Apple specific gcc compiler options for development on Mac OS X

The latest Apple gcc available on the web in source code is "gcc3-1151", a gcc 3.1 variant.

Manually applying "gcc-3.1.1.diff" works, except for the patch to system.h, as Apple has changed:

#define GCCBUGURL "URL:http://www.gnu.org/software/gcc/bugs.html"

into

/* APPLE LOCAL report bugs to Apple 2001-09-14 sts */ #define GCCBUGURL "URL:http://developer.apple.com/bugreporter"

and gpc tries to patch it also. Of course, this can be fixed easily.

The build progresses very nicely, but ends with (what appears to be) the linking of gpc1:

So, apparently, some routines and/or compiler defines are missing.

Currently, I am investigating this further. I found "_pfe..." routines in an Apple specific subdirectory "pfe" in the gcc directory. Consequently, I try to understand make files and build rules, so that I can add routines and compiler defines to the gpc link. Of course, any hints are welcome.
