Hello,

It turned out, the problem is how to tell include directiories when
generating a library. We use

---snip---
...
flibs = [('fortmisc',
          {'sources': lib_src,
           'include_dirs': [os.path.join("lib", "numfort")],
           'macros':[]},),]
...
setup(...
      libraries=flibs,
      ...)
...
---snip---

and setting 

set_verbosity(3)

gives

---snip---
...
Running os.system('( /usr/software/fitools/opt/intel/compiler70_l_fc_pc_7.1.038/ia32/bin/ifc -72 -w90 -w95 -KPIC -cm -O3 -unroll -tpp5 -xM -c lib/numfort/NB.F -o build/temp.linux-i686-2.2/lib/numfort/NB.o ; echo $? > /tmp/@6992.7 ) 2>&1 | tee /tmp/@6992.6 ')
...
---snip---

I guess the the correct fix lies in _compiler in fcompiler.py. The line

---snip---
        command = compiler + cc_args + s_args + o_args + extra_postargs
---snip---

should be

---snip---
        command = compiler + cc_args + s_args + o_args + extra_postargs + pp_opts
---snip---

(at least this works for me). Of course "NB.F" only compiles with
another (helpfull) patch to fcompiler.f. I changed 

---snip---
    language_map = {'.f':'f77',
                    '.for':'f77',
                    '.F':'f77',
                    '.ftn':'f77',
                    '.f77':'f77',
                    '.f90':'f90',
                    '.F90':'f90',
                    '.f95':'f90'}
---snip---

and

---snip---
    src_extensions = ['.for','.ftn','.f77','.f','.f90','.f95','.F','.F90']
---snip---

Probably 'language_map' shold reflect that '.F' and '.F90' files
should be preprocessed using fpp, and fpp must be explicitly switche
on on some platforms.

Kind regards
