The '-I' is left out in front of each directory that should be included for
the IDL-files.  I have a sane GNU tool chain, but I'm not sure if all my
GNU tools are being used (since Solaris provides crippled versions of some
of the programs) ....

I'll attach my config.log, and meanwhile I'll edit my makefiles ....
