start of sigcm project - a small port of libsigc++ for GNUstep, a usable tarball - WIP,GPLv2

[elvish healer]

Hi all,

There's a small feature list implemented, you can instantiate a signal, connect 
it and emit. Written out of the blue, uses GNUstep library makefile - WIP.

It is hosted at http://code.google.com/p/sigcm , there's one tarball and git 
has the latest version.

sigcm defaults to void* function return values and arguments, I do not intend 
to write a objc++ version as libsigc++ can be used for that. Then again, I want 
to use it in GNUstep's ObjC.

Enjoy,
EH
