[Vortex] Patch for axl C99 incompatibility

Recent versions of axl, and thus vortex, aren't compatible with C99 --  
their public headers result in syntax errors when #included. This is  
because axl_decl.h contains a typedef declaration for "bool", which is  
already a built-in type in C99.

The following one-line patch fixes the problem. It was already present  
in the older copy of axl I had before upgrading today; I no longer  
remember whether I made the change myself, or whether it was in the  
official sources as of last summer but somehow vanished since then.
