Thanks to Paul A Sand <pas@unh.edu> and Karl Vogel <kvo@seagha.com> for
their suggestions. Paul suggested:
Haven't tackled gcc yet, but
I had a similar (maybe the same) problem in compiling gdb.
My notes say I included the lines
#include <float.h>
#define NAN DBL_QNAN
in libiberty/floatformat.c to make things work better.
Hope this helps, no warranties expressed or implied, etc.

...and Karl said:
This looks familiar.. I bumped into this myself when porting OpenPKG-current
(http://www.openpkg.org) to Tru64 V5.1-1.
The solution is to add '-ieee' to the compile flags.
-----
Doing the two suggestions allowed the compile to succeed.
