64bit compile fails on Solaris 10

[John Center <john.center@villanova.edu>]

Hi,

I'm trying to compile OpenLDAP v2.4.13 on Solaris 10 using Sun Studio 
12.  Everything is building fine until it gets to slapd itself.  It 
fails linking .libs/slapdS.o:

rm -f .libs/slapd.nm .libs/slapd.nmS .libs/slapd.nmT
creating .libs/slapdS.c
(cd .libs && cc   -c "slapdS.c")
rm -f .libs/slapdS.c .libs/slapd.nm .libs/slapd.nmS .libs/slapd.nmT

cc -g -fast -fsimple=0 -fns=no -xtarget=ultraT1 -xarch=sparcvis2 -m64

cc: Warning: -xarch=v9 is deprecated, use -m64 to create 64-bit programs
ld: fatal: file .libs/slapdS.o: wrong ELF class: ELFCLASS32

I think slapdS.c is generated dynamically by ltmain.sh, seen in the line:
	(cd .libs && cc   -c "slapdS.c")

I don't know what slapdS.c does, but I think "-m64" needs to be passed 
to cc here; unfortunately I don't know how to do it.  I've searched 
through the mail archives w/o much luck.  Could someone please explain 
to me what I'm missing?

Thanks.
