Detection of main bundle path in NSBundle

[Mathias Bauer]

Hi,

the NSBundle implementation detects the main bundle path by evaluating 
the environment variables LIBRARY_COMBO, GNUSTEP_HOST_CPU and 
GNUSTEP_HOST_OS.

IMHO the GNUSTEP_HOST would be even better, at the end it is what also 
the compiler uses to detect the target platform to build for.

Any objections against checking for GNUSTEP_HOST in NSBundle also?

Regards,
Mathias
