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
