Hi.
I usually cross-build an application with mingw32 and mingw64 and have no
problems, but since a couple of weeks ago I'm not able to build the application
because any standard library include in my C++ code will produce errors.
The error seems to be that the compiler is looking in the wrong places to build
the code. I always get a similar error like:
x86_64-w64-mingw32-g++ -O2 -g -pipe -Wall -fexceptions
--param=ssp-buffer-size=4 -mms-bitfields -MD -MP -DDEBUG -DEE_DEBUG

Looking into the include paths I get these:

I seems that both compilers are getting the headers files from:
/usr/include/c++/12/
/usr/include/c++/12/x86_64-suse-linux/
I don't think that it's correct, it should be looking in the MinGW include
paths.
I can confirm that removing both incorrect include paths compilation works:

Also parameter:
-B /usr/bin/x86_64-w64-mingw32-
or
-B /usr/bin/i686-mingw32-
Must be passed in order to be able to build anything. This was not the case a
few months ago.
Reproducible: Always
Steps to Reproduce:
1. Try to cross-compile any C++ file with mingw32 or mingw64
Actual Results:
Include file error
Expected Results:
Successful compilation
