[LLVMdev] VMKIT problem

[Nicolas Geoffray]

Hi Nataraj,

OK, this a problem with GNU Classpath that can not be compiled with gc 
4.3 anymore. You have to change line 89 of cpproc.c to put the result of 
chdir in a temporary variable, so that the new "warn_unused_result" 
annotation on chdir does not report an error.
