glib2 and pthread on solaris

[Michael Weiser <michael weiser dinsnail net>]

Hi there,

how well tested is the following part of recent (>=2.11) glib's
configure?

      *-solaris*)
        # These compiler/linker flags work with both Sun Studio and gcc
        # Sun Studio expands -mt to -D_REENTRANT and -lthread
        # gcc expands -pthreads to -D_REENTRANT -D_PTHREADS -lpthread
        G_THREAD_CFLAGS="-D_REENTRANT -D_PTHREADS"
        G_THREAD_LIBS="-lpthread -lthread"
        ;;

On Solaris 10 SPARC64 with binutils-2.17 and gcc-4.2.0 in 64bit mode
(configured for target sparc64-sun-solaris2.10 without multilib) this
leads to the following error message:

When removing the above section it compiles cleanly using:

/bin/bash ../../libtool --mode=link gcc  -O2 -pipe -I/usr/local/include
-Wall  -L/usr/local/lib -Wl,-rpath,/usr/local/lib -o closures
closures.o ../../glib/libglib-2.0.la ../../gobject/libgobject-2.0.la
