Re: how to call C (non-intel C compiler) from ifort (intel fortran)?

Intel changed the default calling convention from __stdcall to __cdecl,
when it took over the CVF. So, either adjust it on C side, or change the
calling convention on Fortran side. In addition, the way how CHARACTER
arguments are passed is also changed -- the hidden length is now passed
at the end of argument-list rather than immediately following the string
argument.
