For MacOS X it was just a matter of passing -lintl and setting up the  
correct library search path.

Ah. Nice to learn...

The default bash of MacOS X says:

GNU bash, version 2.05b.0(1)-release (powerpc-apple-darwin8.0)
Copyright (C) 2002 Free Software Foundation, Inc.

But it is no problem to get and install a newer one (3.2.9) through  
MacPorts...

Well - it IS a problem.

It is installed in /opt/local/bin/bash - and therefore #!/bin/bash  
still calls the old one...
Maybe, I have to write some patch



Another question: Is it difficult to add Objective-C and Objective-C+ 
+ to
the configuration flags? Would be of major help for embedded GNUstep.

Best regards,
Nikolaus
