Don't remove AC_PROG_CPP our headerfile and library checking macros depend on it. Unbreak configure.ac

Provide trivial work-around for users of obsolete autoconf

- configure.ac: autoconf 2.59c is not yet supported in Cygwin, added Wine support for ActiveX plugin

- Some cleanup

Can we?

* run update-po

TODO: test for xpidl in /usr/lib{,64}/seamonkey too.

Afterall, ts is a plugin, and is probably as useful if not more.

You can still disable it manually...
and well, you've had six months to fix your build system.

* Does nothing useful at the moment (only useless device probing)
* The purpose would be to make an access-demux and an access sub-module reusing part of the code
* Access to a webcam or an analog card without an encoder (bt878) would help the development

* configure.ac: enabled Obj-C exceptions in the OBJCFLAGS (they're currently used by AppleRemote only, but we should extend them to further classes)
* AppleRemote.*: added svn id and proper notes about the MIT-style and GPL dual licensing

 * JAVA_HOME is set
 * a java compiler compiles

* gnutls needs -lintl ldflag with newer versions. It's so nice if packages keep track of what libs they use....... hint hint
