Greetings, 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. Ultimately, I'd like to be in a position to fix the GetMicroSecondTime routine, which does not work in Windows, and has not done so for years.
