9 years ago It's a heuristic, of course we can't know which things are paths and which aren't. Disabling it globally will get you a fairly useless MSYS2. In fact, you may as well use Cygwin in that case. But this isn't a reason not to provide this capability as there may be some extreme edge cases when such a blunt tool is useful.

1 year ago I have a similar problem running cl of ms build tools in mingw32-make when I try to build fbalpha, the error line shown is https://github.com/barry65536/FBAlpha/blob/416948158d88ba17f87813419ddc3c1209ef68c0/makefile.vc#L456. I printed the executed command, tried to run it in the cmd directly and it was ok. So the problem maybe the execution shell is not cmd but bash in msys2/mingw32. I also add echo $$SHELL in makefile which it printed /usr/bin/bash.
I tried to executed cl /h in mingw32 shell, /h seemed interpreted different then cmd.
cl command run in the cmd shell:

Because the interpretation of cl /h in cmd and mingw32 is quite different. /h in mingw32 shell seemed expanded or modified. If /h arguments passed as is, the make process would no problems.

I'm finding MSYS2's automatic mangling of environment variables1 2 when running native Win32 applications to be quite problematic. For example, any environment variable whose value begins with a forward slash appears to be interpreted as a UNIX path and is rewritten to be prefixed with "c:/msys64" when accessed by a Win32 app.
Relying on heuristics like this seems really error prone, so I'd like to request the ability to disable this behaviour globally.
