Fixed in the current CVS version of the stable branch but this means
it'll be fixed in 2.1.5 when that is released.  The problem is that
one object file (kernel2.o) which should be mentioned in the Makefile
is omitted.

The fix affects config/Makefile.SH and files in src/kernel/sparcv8/;
I can send you what's needed directly unless you want to go to the
CVS repository  (see CVS.txt in the base directory)  and pick up the
latest stable branch yourself.
(The tag name is: cvs update -r release-2-1-patches )

Hint #1: use fpversion to obtain a hint about -xcache etc. options
for an optimized build.

Hint #2: use -fsimple=1;  the Sun FD6U2 cc 5.3 defaults to -fsimple=2
at higher optimization levels, which is deadly to PARI.

(All these options must be given _after_ the -fast macro if -fast
is used, or the -fast expansion will override them.)
