.IP M4()
.IP env.M4()
A function that converts a file name into a File instance relative to the
target being built.
+.IP FRAMEWORKSFLAGS
+On Mac OS X,
+frameworks options to be addad at
+the end of a command
+line building a loadable module.
+
.IP GS
The Ghostscript program used to convert PostScript to PDF files.
.IP LATEXFLAGS
General options passed to the LaTeX structured formatter and typesetter.
+.IP LDMODULE
+The linker for building loadable modules.
+By default, this is the same as $SHLINK.
+
+.IP LDMODULECOM
+The command line for building loadable modules.
+On Mac OS X, this uses the $LDMODULE,
+$LDMODULEFLAGS and $FRAMEWORKSFLAGS variables.
+On other systems, this is the same as $SHLINK.
+
+.IP LDMODULECOMSTR
+The string displayed when building loadable modules.
+If this is not set, then $LDMODULECOM (the command line) is displayed.
+
+.IP LDMODULEFLAGS
+General user options passed to the linker for building loadable modules.
+
+.IP LDMODULEPREFIX
+The prefix used for loadable module file names.
+On Mac OS X, this is null;
+on other systems, this is
+the same $SHLIBPREFIX.
+
+.IP LDMODULESUFFIX
+The suffix used for loadable module file names.
+On Mac OS X, this is null;
+on other systems, this is
+the same $SHLIBSUFFIX.
+
.IP LEX
The lexical analyzer generator.
- Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
$CCFLAGS, and -mwindows to $LINKFLAGS.
+ From Michael McCracken:
+
+ - Add a new "applelink" tool to handle the things like Frameworks and
+ bundles that Apple has added to gcc for linking.
+
+ - Use more appropriate default search lists of linkers, compilers and
+ and other tools for the 'darwin' platform.
+
+ - Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
+ and a shared library on other systems.
+
+ - Improve SWIG tests for use on Mac OS X (Darwin).
+
From Elliot Murphy:
- Enhance the tests to guarantee persistence of ListOption
