Hi, Yes, sorry about that, I’m trying to reproduce it locally but no luck so far.. (waiting for a clean checkout to finish now) But the fix is probably to swap the definition of Excn.h and PosixSource.h in RtsMain.c or moving Excn.h to the bottom of the include list. Something in Excn.h must be using _mingw.h which will define the macro if not defined. Adding PosixSource to the top would make sure it is defined before anything else. Regards, Tamar From: Austin Seipp Sent: ‎Wednesday‎, ‎March‎ ‎4‎, ‎2015 ‎00‎:‎14 To: Simon Peyton Jones Cc: ghc-devs@haskell.org This must be fallout from the VEH handler change I pushed earlier - 5200bdeb26c5ec98739b14b10fc8907296bceeb9. I'll try to fix/revert shortly. On Tue, Mar 3, 2015 at 4:30 PM, Simon Peyton Jones <simonpj@microsoft.com> wrote:

Thanks for a prompt fix!

My apologies again, my last few builds were using ./validate --no-clean by my are-validating.mk was missing so it wasn’t compiling with -Werror.
