You shouldn't have to point to it, the compiler is supposed to be able
to find its own libraries without you telling it anything beyond
-lgfortranbegin.

This normally should contain a lot more, such as the Windows system32
directory.  But in any case, PATH not affect where libraries are
searched by the linker.

As I said before this variable is not used on MinGW.

You should not need to set this at all.  I don't know if it's causing
the problem having it set, but try running the command below again
without it set.

You could also go back to using gfortran to link with -lstdc++ -lsupc++.
