Purpose:
    DEC UNIX port
Description:
    Windows port caused problems on DEC UNIX.
    Names of C functions called from F90 subroutines were converted
    to UPPER case while DEC UNIX expected them to be in lower case.
Solution:
    Added special DEC compiler directives to avoid the conflict on two
    systems
Platforms tested:
    Windows98, DEC UNIX, Linux
