PR win32/25302 notes that gdb will crash when trying to "run" even a simple program on Windows. The essential bug here is that the BFD cache can easily be corrupted -- I have sent a separate patch for that. The particular reason that the cache is corrupted on Windows is that gnulib overrides "stat" to make it do timezone adjustment -- but BFD does not use this version of stat. The difference here triggers the latent cache bug, but can also cause other bugs as well; in particular it can cause spurious warnings about source files being newer. This patch simply removes the stat override on mingw, making gnulib and BFD agree. I tested this by backing out the local AdaCore changes to work around this bug and then verifying that I could reproduce it. Then, I applied this patch and verified that "run" works again. 2020-09-08 Tom Tromey <tromey@adacore.com> PR win32/25302: * update-gnulib.sh: Apply stat patch. * patches/0001-use-windows-stat: New file. * import/m4/stat.m4: Update. * configure: Rebuild.
