[svn-r10970] Purpose: New feature/bug #350 fix

Description:
             When compiler flag was used to set the size of Fortran integer
             to 8 bytes, library would fail.

Solution:
             Cleaned up the code; added detection of Fortran INTEGER type size
             and appropriately defined int_f type for C-stubs routines.

Platforms tested:
             Solaris 2.8 32 and 64-bit, AIX 5.1 64-bit parallel
             PGI Fortran with -i8 flag on heping
             Absoft Fortran with -i8 flag on heping
             g95 on mir (Fortran integer is 8 bytes by default that cannot be
                         changed - compiler bug ;-)
             AIX Fortran with -qintsize=8 32 and 64-bit modes on copper
