Order of directory search for .mod files.

[David Ham]

We have recently noticed that gfortran appears to pick up .mod files 
from default locations in preference to directories specified by -I 
arguments on the command line. So, for example, if foo.mod is in 
/usr/include and foo.mod is in /home/bar/somedir and the user types:

gfortran -I/home/bar/somedir ...

then gfortran will pick up /usr/include/foo.mod . This causes particular 
problems when the system gfortran distributed with the OS is, say, 4.2 
and a user has installed gfortran 4.3 since nothing the user can specify 
on the command line will prevent .mod files from installed packages 
(generally compiled with 4.2) being used.

Is this the intended behaviour of gfortran or is this a bug?

Regards,

David
