--- Comment #1 from Brecht Sanders <brechtsanders at users dot sourceforge.net> ---
Apparently this issue is not related to the .exe extension, but rather to where
it is looking for cc1.exe.

If somepath/bin is where gcc.exe lives than it helpst to add
somepath/libexec/gcc/x86_64-w64-mingw32/12.1.0 to the PATH to around this
issue.

But this should not be necessary.

I also find it strange that I don't have this issue with the MSVCRT build of
MinGW-w64, but I do have the issue with the UCRT build of MinGW-w64.

Is there a different path or architecture triplet at play for UCRT?
