pgsql 7.2.2: problem compiling on Sol 8

I'm trying to compile PGSQL 7.2.2 to run with PHP and Apache on Solaris
8. The compilation appears to go OK, but, when I load Apache, I get

Syntax error on line 237 of /etc/apache/httpd.conf:
Cannot load /usr/apache/libexec/libphp4.so into server: ld.so.1:
/usr/apache/bin/httpd: fatal: libgcc_s.so.1: open failed: No such file
or directory
/usr/apache/bin/apachectl start: httpd could not be started

I pinned this down to

ldd /usr/local/pgsql/lib/libpq.so.2
        libgcc_s.so.1 =>         (file not found)


I am using gcc 3.1.1, which is installed in a non-default location. My
command sequence is:

setenv LD_LIBRARY_PATH
/nerc/packages/gcc/3.1.1/lib:/nerc/packages/gcc/3.1.1/lib/sparcv9
setenv LDFLAGS "-L/nerc/packages/gcc/3.1.1/lib
-R/nerc/packages/gcc/3.1.1/lib"
configure --quiet --with-libraries=/nerc/packages/gcc/3.1.1/lib
--with-includes=/nerc/packages/gcc/3.1.1/lib
gmake

then, as root, gmake install

I see from browsing the email lists that this problem has been
encountered before, May 2001 was the earliest reference, but have not
been able to find a solution.

Can anybody help? Reply to me directly, I will summarise.

I also tried 7.1.3; this gave me

heaptuple.c:760: `MAXIMUM_ALIGNOF' undeclared (first use in this
function)
gmake[4]: *** [heaptuple.o] Error 1
gmake[4]: Leaving directory

thanks in advance, Dick
