I don't know what you're trying to say, but GNU make (on UNIX systems)
_is_ absolutely case sensitive.  There is no question about it.

There is a compile option you can use and rebuild make; add a line like:

  #define HAVE_CASE_INSENSITIVE_FS

to your config.h file after running configure.

This option is never tested on UNIX (it's used by some of the ports) so
I can't say how well it will work.


Your other option is to change the rule that generates the .mod file so
that it renames the file to be lowercase.  So you have a rule like this:

  %.o %.mod : %.F90
            ...
            @mv `echo $* | tr a-z A-Z`.mod $*.mod

Now even though the compiler generates the file as FOO.mod, the make
rule will rename it to foo.mod.
