+dnl interface stubs, but they're broken, configuring them for inter-process
+dnl mutexes doesn't return an error, but it doesn't work either. Second,
+dnl there's a bug in SunOS 5.7 where applications get pwrite, not pwrite64,
+dnl if they load the C library before the appropriate threads library, e.g.,
+dnl tclsh using dlopen to load the DB library. Anyway, by using LWP threads
+dnl we avoid answering lots of user questions, not to mention the bugs.

+dnl @synopsis CHECK_ZLIB()
+dnl
+dnl This macro searches for an installed zlib library. If nothing
+dnl was specified when calling configure, it searches first in /usr/local
+dnl and then in /usr. If the --with-zlib=DIR is specified, it will try
+dnl to find it in DIR/include/zlib.h and DIR/lib/libz.a. If --without-zlib
+dnl is specified, the library is not searched at all.
+dnl
+dnl If either the header file (zlib.h) or the library (libz) is not
+dnl found, the configuration exits on error, asking for a valid
+dnl zlib installation directory or --without-zlib.
+dnl
+dnl The macro defines the symbol HAVE_LIBZ if the library is found. You should
+dnl use autoheader to include a definition for this symbol in a config.h
+dnl file. Sample usage in a C/C++ source is as follows:
+dnl
+dnl #ifdef HAVE_LIBZ
+dnl #include <zlib.h>
+dnl #endif /* HAVE_LIBZ */
