-------^^^^^^^^^^

Could you provide the relevant output of config.log ?
Or even better look at it before and check whether it provides the
relevant hints to solve this ?

In the line starting with 'checking for Fortran libraries of g95...'
I see references to MinGW 3.4.5 (presumably the official version) as
well as some MinGW 4.0.3 (not an official version).

Apparently you are mixing libraries here. Not sure this is a problem
but at least that looks suspicious.

Best,
Michael
