In 64-bit mode, where the implicit "int" return type is a 32-bit value  
and the real return value is a 64-bit value, yes, this will cause  
problems.

In the string.h header on my system, defining _REENTRANT appears to be  
one of the ways to get the declaration for strdup() to be used.  I'm  
using:

cc: Sun C 5.9 SunOS_sparc 2007/05/03

What does it take under 5.8?
