+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 assembly-language files.

+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 We distinguish between THREAD_LIBS_LOCAL and

+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.
