Changes 1.17:
* Derek Lamb's patch to avoid an uninitialised variable error.
* Diab Jarius's Solaris Studio 10 patch and his gfortran patch (with mods).
  Note g77 is still the default if both it and gfortran are present.
* Rob's big Win32 patch (Nov 2010 version)
* IMPORTANT. Added in simplification of GNU fortran compilers
  (g77, gfortran, g95, fort77) etc. suggested by Tim Jeness. I used his code
  but made a slightly different implementaion introducing a 'Generic' 'GNU'
  database entry to which others point.
  This also superceded some of the above patches.
  Hope this works!
* Removed places where .gcclibs() is added to the link line, this appears to
  no loner be necessary. Routine left in there (but orphaned) just in case.
