[MITgcm-devel] genmake2 fails with netcdf on SUN

[Martin Losch]

More awk troubles:
SunOS's awk (oawk) doesn't like the "toupper" command:
> rays1::MITgcm> echo ALLOW_something | awk '{print toupper($0)}'
> ALLOW_something
> rays1::MITgcm> echo ALLOW_something | nawk '{print toupper($0)}'
> ALLOW_SOMETHING
> rays1::MITgcm> echo ALLOW_something | gawk '{print toupper($0)}'
> ALLOW_SOMETHING
This causes serious problems because all -DALLOW_PKG become -DALLOW_pkg 
etc. My "Unix is a Nutshell" from 1994 even says that "toupper" is only 
available in gawk, but apparently it works also in nawk.

After (quick-)fixing this problem (replaced $AWK with gawk in the 
instances toupper appears in genmake2), everythings compiles and runs 
with /usr/bin/awk on SunOS, Solaris 5.9.

Again, do we care about this? Or is it better to stick with gawk/nawk 
and have these specified in all sunos_sun4u_* build options files?
