That's unfortunate; I was hoping that those redundant __msvcrt_*, and __mingw_* aliases would no longer be needed. > I don't see a new gcc-core-9.2.0-1-mingw32-bin.tar.xz on the MinGW > download site. I've rebuilt, and posted a complete gcc-9.2.0-2-mingw32 package set on FRS; it is linked with wsl-5.4. Does it resolve the issue? > Alternatively, you could reinstate these functions in libmingwex, > which might be a smaller fuss... I could have done this, of course. It might have been a quicker fix, but not really any easier, (since I didn't need to change anything for the GCC rebuild), and I prefer to have the namespace pollution by the redundant symbolic aliases cleaned up ASAP. -- Regards, Keith.
