>Description:

The pgcc and pg++ scripts installed as part of the devel/mit-pthreads
package print inappropriate warning messages when invoked with any
command line option that suppresses the linking stage of compilation,
except for the "-c" option which does work correctly.  Options triggering
the undesired behaviour include -E, -M, and -S.

The warning messages are more than just a cosmetic problem, because
they cause certain configure scripts generated by GNU Autoconf to
fail.  These scripts attempt to find a working C preprocessor by
running "$CC -E", and consider any output on stderr an indication of
failure.  Hence, "configure CC=/usr/pkgsrc/pthreads/bin/pgcc" may fail
to find any working C preprocessor at all.

>How-To-Repeat:

    $ touch test.c
    $ /usr/pkg/pthreads/bin/pgcc -E test.c
    # 1 "test.c"
    gcc: -lpthread: linker input file unused since linking not done
    gcc: -lm: linker input file unused since linking not done
    gcc: -lgcc: linker input file unused since linking not done
    gcc: -lpthread: linker input file unused since linking not done

>Fix:

Add the following patch to the the
/usr/pkgsrc/devel/mit-pthreads/patches directory.
This patch is for the 1.3.2 pkgsrc:

--- scripts/pgcc.sh.orig	Fri Sep  1 01:43:39 1995
