[svn-r21525] Description:

Removed hard-coded check of compatible Fortran 2003 compilers; replaced 
with simple check program for required F2003 features. Does not check for 
known bugs in compilers, tests will fail for those compilers.

Tested: jam (gnu 4.1, 4.5, intel, pgi)
        linew (default)
