Appologies to all, I have been blind!

Disregard my proposed patches. One of users on Tru64 mailing list
pointed me to a correct solution - add "-ieee" to CC flags. I took a
look at templates for OSF1 in PgSQL and they read:

CFLAGS="-O -ieee"

Since I was putting my own definition for CFLAGS, I left out "-ieee". I
have reverted ./src/include/port/osf1.h to the the original and changed
CFLAGS in ./src/Makefile.global to include "-ieee". Then I rebuild
./src/backend/utils/adt/float.o (I'll rebuild the whole PostgreSQL in a
moment) and ran regression tests.

All 93 tests passed.

So, again, my apologies to all, no change neccesary.

Nix.
