[PATCH] bfd: handle codepage when opening files on MinGW

Hi Luis,

So that would imply a missing #include of a system header, yes ?

Do you know which header provides the required prototype ?

The code is currently conditional upon __MINGW32__ being defined.  Perhaps
that check needs to be extended/changed to reference a different preprocessor
symbol ?

Cheers
