-   Condition variables can be used for waiting until a condition

-   waiting for them.

-   Condition variable:
-     Type:                gl_cond_t

-     Initializer:         gl_cond_define_initialized(, name)
-     Initialization:      gl_cond_init (name);
-     Waiting:             gl_cond_wait (name, lock);
-     Timed wait:          bool timedout = gl_cond_timedwait (name, lock, abstime);
-                          where lock is a gl_lock_t variable (cf. <glthread/lock.h>)
-     Signaling:           gl_cond_signal (name);
-     Broadcasting:        gl_cond_broadcast (name);
-     De-initialization:   gl_cond_destroy (name);
-   Equivalent functions with control of error handling:

-     Timed wait:          err = glthread_cond_timedwait (&name, &lock, abstime);

-   whether a function pointer's value, such as &pthread_mutex_init, is
-   non-NULL.  However, some versions of GCC have a bug through which, in
-   PIC mode, &foo != NULL always evaluates to true if there is a direct
-   call to foo(...) in the same function.  To avoid this, we test the
-   address of a function in libpthread that we don't use.  */

-   Limitations of this substitute, when used in a C89 environment:
-
-       - <stdbool.h> must be #included before the '_Bool' type can be used.
-
-       - You cannot assume that _Bool is a typedef; it might be a macro.
-
-       - Bit-fields of type 'bool' are not supported.  Portable code
-         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
-
-       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
-         performed in such a way that every nonzero value gets converted
-         to 'true', and zero gets converted to 'false'.  This doesn't work
-         with this substitute.  With this substitute, only the values 0 and 1
-         give the expected result when converted to _Bool' or 'bool'.
-
-   Also, it is suggested that programs use 'bool' rather than '_Bool';
-   this isn't required, but 'bool' is more common.  */

-   (see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'

+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs

+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:

+# SYNOPSIS
+#
+#   AX_BOOST_THREAD
+#
+# DESCRIPTION
+#
+#   Test for Thread library from the Boost C++ libraries. The macro requires
+#   a preceding call to AX_BOOST_BASE. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_THREAD_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_THREAD

-dnl From Paul Eggert and Derek Price.

-dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
-dnl
-dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
-dnl 'include' otherwise.
-dnl
-dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
-dnl supports it in the special case that it is the first include directive in
-dnl the given file, or to 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.
