+dnl   QTHREADS_CONFIGURE configures the QuickThreads package.  The QT
+dnl   sources should be in $srcdir/qt.  If configuration succeeds, this
+dnl   macro creates the appropriate symlinks in the qt object directory,
+dnl   and sets the following variables, used in building libqthreads.a:
+dnl      QTHREAD_LTLIBS --- set to libqthreads.la if configuration
+dnl         succeeds, or the empty string if configuration fails.
+dnl      qtmd_h, qtmds_s, qtmdc_c, qtdmdb_s --- the names of the machine-
+dnl         dependent source files.
+dnl      qthread_asflags --- flags to pass to the compiler when processing
+dnl         assembly-language files.
+dnl
+dnl   It also sets the following variables, which describe how clients
+dnl   can link against libqthreads.a:
+dnl      THREAD_PACKAGE --- set to "QT" if configuration succeeds, or
+dnl         the empty string if configuration fails.
+dnl	 THREAD_CPPFLAGS --- set to `-I' flags for thread header files
+dnl	 THREAD_LIBS_LOCAL --- linker options for use in this source tree
+dnl	 THREAD_LIBS_INSTALLED --- linker options for use after this package
+dnl	    is installed
+dnl   It would be nice if all thread configuration packages for Guile
+dnl   followed the same conventions.
+dnl
+dnl   All of the above variables will be substituted into Makefiles in
+dnl   the usual autoconf fashion.
+dnl
+dnl   We distinguish between THREAD_LIBS_LOCAL and
+dnl   THREAD_LIBS_INSTALLED because the thread library might be in
+dnl   this tree, and be built using libtool.  This means that:
+dnl	 1) when building other executables in this tree, one must
+dnl	    pass the relative path to the ../libfoo.la file, but 
+dnl	 2) once the whole package has been installed, users should
+dnl	    link using -lfoo. 
+dnl   Normally, we only care about the first case, but since the
+dnl   guile-config script needs to give users all the flags they need
+dnl   to link programs against guile, the GUILE_WITH_THREADS macro
+dnl   needs to supply the second piece of information as well.
+dnl
+dnl   This whole thing is a little confused about what ought to be
+dnl   done in the top-level configure script, and what ought to be
+dnl   taken care of in the subdirectory.  For example, qtmds_s and
+dnl   friends really ought not to be even mentioned in the top-level
+dnl   configure script, but here they are.
