It's a nuisance, but doesn't cause real problems
(warnings can be ignored).
You could delete the -D_d=E in genmake.

-xtypemap has been introduced by Alistair.
Does not seem to be compatible with older Sun compilers.
You may want to revert to the older FFLAGS (i.e. -r8 -i4),
see.e.g. the difference page of CVS version 1.59 and 1.60 of genmake
http://mitgcm.org/cgi-bin/cvsweb.cgi/MITgcm/tools/genmake.diff?r1=1.59&r2=1.60&only_with_tag=MAIN&f=h

The source of this error is a missing argument in an
#ifdef statement.
My fault, as I quickly tried to incorporate the calendar and
external forcing package into the MITgcm stand alone
to make it available to Francis.
It's no problem on the linux g77 compilers which is why
I didn't notice it.
Fix: in line 106 of packages_readparms.F
the "#ifdef" should be #ifdef ALLOW_CALENDAR".

Cheers
Patrick
