[ILUG] C question [OT]

[Thomas Bridge]

I know this is probably off topic, but I'm trying to make this code work 
under RH 6.2

I have a piece of code which does a process, but I only want one part of 
the code to be compiled, depending on the compile time options.

I was trying to do this by means of the following:

#ifdef USE_CODEBASE1
	/* Code here */
#elsifdef USE_CODEBASE2
  	/* alternative code here */
#else
	/* Default code here */
#endif

Any ideas what I'm doing wrong?    I think it must be the #elsifdef part.
