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.
