This is a patch to the MIT pthreads package version 1.60 beta2 for Linux 1.2.x
systems with the ELF object format.

To get shared libraries, add -fPIC to the CFLAGS in GNUmakefile and the 
following lines:

obj/libpthread.so.1.60: ${REALOBJS}
	cd obj && \
		${CC} -shared -o libpthread.so.1.60 ${CFLAGS} ${OBJS} &&\
		cd ..

and change the all-lib line to:

all-lib : libpthread.a obj/libpthread.so.1.60

Questions about pthreads to pthreads@mit.edu, about this patch to hhc@mit.edu.
