[LLVMdev] Problem with stock llvmc configuration for C

They're indeed mentioned, but somehow they were not added to the  
switch-statements in the corresponding parsing functions for the  
various configuration options. I attached a patch in which this is  
resolved, as well as two other bugs:
  * an off-by-one error in a loop copying a command's arguments into  
an array (first argument was dismissed; garbage added at the end);
  * %...%'s in a command name were not substituted, whereas they were  
in the command's arguments.

The patch solved things for me, but it's not perfect yet.

OK.

Kind regards,

PS: I recently saw an email passing by in which someone else was  
talking about a patch for llvmc. Has that one been committed yet?
