[Mono-list] DllImportMap support in mono?

[Jonathan Pryor]

Mono chose to solve this in a different way.  Mono uses a "config" file
(located in $prefix/etc/mono/config), which is an XML file with the
following structure:

	<configuration>
	  <dllmap dll="cygwin1.dll" target="libc.so.6" />
	  <dllmap dll="gtkhtml-3.0" target="libgtkhtml-3.0.so.2" />
	  <!-- ... -->
	</configuration>

The "dll" should be the same string as the library name used in the
DllImport statement, and "target" is the library that mono should
actually load.

The config file is platform-dependent, so the Unix version will have
different "target" values than the Win23 version.

By convention, Mono-written assemblies uses the Win32 library names in
DllImport statements (so Gtk# DllImports "libgtk-win32-2.0-0.dll"),
allowing the assemblies to run unchanged under .NET.  Mono provides the
config file to change this for mono-supported platforms (Linux).
