+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.
