Hi,

Platform Slackware linux 9.1/ Linux 2.6.4

I did a make distclean and ./configure --enable-thread-safety. The build 
aborted with following error messages

make[4]: Leaving directory `/home/shridhar/postgresql/pgsql/src/port'
gcc -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -Wmissing-declarations

The relevant configure messages read 
-------------
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
-------------

Here is relevant portion of src/Makefile.global

-------------
PTHREAD_CFLAGS		= -pthread -D_REENTRANT -D_THREAD_SAFE 
-D_POSIX_PTHREAD_SEMANTICS
PTHREAD_LIBS		= 
LIBS = -lz -lreadline -ltermcap -lcrypt -lresolv -lnsl -ldl -lm 
-------------

It worked after I manually added -lpthread to LIBS and did a make clean;make

Regards
 Shridhar
