I'd rather like to see MinGW builds for the upcoming GnuCOBOL 2.0 release than a VisualStudio build just "because it compiles directly and the MinGW build does not". Concerning diff this is "only" a testsuite issue but I can hope you can help me clearing things up. It all started with running the testsuite and mostly getting failures. After some investigations (and fixing a borked -R linker parameter) we found that nearly everything works - but the testsuite still fails with the output: C:\msys64\mingw64\bin\diff.exe: -: Invalid argument The user tried hard in the hope that rebuilding diffutils would help - he got into the known issue "bug#24304". Side note: I've seen http://lists.gnu.org/archive/html/bug-diffutils/2016-08/msg00052.html and wonder where exactly this bug/wish-list item is tracked (I did not seen any trackers at savannah). I highly suggest to at least add an error during ./configure about the not working environment (maybe adding the link to the bug report) instead of leaving the user with a broken compilation. Back to the main question of this post: Do you have any idea how to fix "-: Invalid argument"? Where should we look at (the user compiled diffutils 3.3 with some unoffical patches but the problem persists). Thank you, Simon
