Fix bug where a preprocessing directive could be mis-evaluated if it occurred immediately after a use of a function-like macro.

This occurred because the code to handle the function-like macro use would read the following token, which could prompt processing of the following preprocessing directive in an inappropriate context.

The following example illustrates the problem (the error message would be printed):

#define A()
#define FOO 1
A()
#if !FOO
# error "shouldn't get here"
#endif
