compilation of PostgreSQL 7.0.2 fails on Sun Solaris 2.5.1 using gcc 2.95.2 in interfaces/libpq++ if GNU ld is first in the $PATH

System Configuration
---------------------
  Architecture (example: Intel Pentium)  	: Sun SPARC

  Operating System (example: Linux 2.0.26 ELF) 	: Sun Solaris 2.5.1

  PostgreSQL version (example: PostgreSQL-7.0):   PostgreSQL-7.0.2

  Compiler used (example:  gcc 2.8.0)		: gcc 2.95.2 19991024 (release)


Please enter a FULL description of your problem:
------------------------------------------------

The generated Makefile for `interfaces/libpq++' starts the

	ld -G -o libpq++.so.3.1 pgconnection.o pgdatabase.o pgtransdb.o
	pgcursordb.o pglobject.o  -L../../interfaces/libpq -lpq -ldl
	-lsocket -lresolv -lnsl -lm -lc

command which depends on the ld version which depends on the user $PATH.

If the GNU ld is first, ld stops with error:

	pgconnection.o: could not read symbols: Bad value

If the `Software Generation Utilities - Solaris/ELF (3.0)' ld from
/usr/ccs/bin is first, everything is OK.

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 
----------------------------------------------------------------------

	tar xfz postgresql-7.0.2.tar.gz
	cd postgresql-7.0.2/src
	./configure --prefix=/usr/local/postgresql-7.0.2 --enable-locale --with-includes=/usr/local/include --with-libraries=/usr/local/lib --with-perl --enable-recode
	PATH=/usr/local/bin:/bin:/usr/ucb:/usr/sbin:/sbin:/usr/ccs/bin gmake

The tail of make log is:

g++ -pipe -g -O2 -I../../backend -I../../include -I../../interfaces/libpq -fPIC -c pgconnection.cc -o pgconnection.o
g++ -pipe -g -O2 -I../../backend -I../../include -I../../interfaces/libpq -fPIC -c pgdatabase.cc -o pgdatabase.o

g++ -pipe -g -O2 -I../../backend -I../../include -I../../interfaces/libpq -fPIC -c pglobject.cc -o pglobject.o
ar crs libpq++.a pgconnection.o pgdatabase.o pgtransdb.o pgcursordb.o pglobject.o
ranlib libpq++.a
ld -G -o libpq++.so.3.1 pgconnection.o pgdatabase.o pgtransdb.o pgcursordb.o pglobject.o -L../../interfaces/libpq -lpq -ldl -lsocket -lresolv -lnsl -lm -lc
pgconnection.o: could not read symbols: Bad value
gmake: *** [libpq++.so.3.1] Error 1

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

I was able to link a shared library using this (maybe more portable than
`ld') command:

	gcc -shared -o libpq++.so.3.1 pgconnection.o pgdatabase.o
	pgtransdb.o pgcursordb.o pglobject.o
