Ladies and Gents,

I've recently installed the Portland Groups's Fortran 90
for Linux on my system (it works!).  However, during the
installation from the cdrom, a install script is executed
that contains a test involving "uname -s" to ensure the
installation is on a system running Linux.  Of course,
"uname -s" on a FreeBSD system returns "FreeBSD" instead
of the expected "Linux".  Thus, I had to alter uname(1) 
to report "Linux" to install the software.  With the
expected availability of more commericial software for Linux,
it seems necessary to provide uname(1) the capability to
report "Linux" in place of "FreeBSD".
