Re: Emacs build fails loading UNICOWS.DLL

[Juan Jose Garcia-Ripoll]

I have printf-debugged. The problem is related to OS_NT being now a macro in Msys2's toolchain. Thus, when Emacs is compiled, OS_NT = OS_9X = 1 !!! See this patch that was submitted to my repo https://github.com/juanjosegarciaripoll/emacs-build/blob/757284e60e13da8341e181b86cda4a7c0d5d079c/patches/0001-Using-other-enum-than-OS_NT-which-is-a-define-in-Win.patch

This means Emacs thinks you are on Windows 9X.  When did you last
updated from Git, and which branch of the repository are you building?
