-dnl Autoconf macros for configuring the QuickThreads package
-
-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 --- the name of the machine-dependent header file.
-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 build-guile 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, qtmdc_lo and
-dnl friends really ought not to be even mentioned in the top-level
-dnl configure script, but here they are.
