I'm trying to compile GPC from sources on Msys, within mingw on 32-bit Windows 7. Is this possible? The gcc-3.4.6/configure appears to work. It patches the GCC 3.4.6 for Pascal. I run the makefile, which proceeds for a while, with warnings like this:

warning: structure 'reg_info_def' used but not defined

Then the compile then fails with:

cc1.exe: error: min-insn-modes.c: Invalid argument

If any of this is familiar, or if I'm missing something obvious, please let me know.

Note that this is failure of gcc to compile one of its files. IME main source of failures compiling gpc are actually failures compiling gcc. So the first thing to try is compiling gcc-3.4.6 _without_ gpc. If failure persist, then ask Mysys/mingw folks what patches are needed to compile gcc. Unfortunatly, Mysys/mingw folks distribute binaries but freqently forget to provide patches and description of tweaks they did to have succesful compilation.
