Yes, but they don't mean the same thing. The intent of the first was 
not to define two char*, but to modify the definition of localSP to 
force a register choice by the compiler.

The SP_REG is a macro that should expand to whatever magic is required 
for your compiler to make it use a particular register.

In GCC, that's usually something like
	# define SP_REG asm("%edi")

Unfortunately, compilers differ considerably in what they require. 
Some may require magic incantations prior to the identifier.

Unless you're using GCC, you should be compiling interp.c, not 
gnu-interp.c. Without including sqGnu.h you should be able to compile
