Change the name if you prefer.

 Wouldn't that be a reserved identifier?

7.26.3 (in 9899:1999) reads: 'Macros that begin with E and a digit or E and an uppercase letter may be added to the
declarations in the <errno.h> header.'
I can find no reference to such identifiers being explicitly reserved (did I miss something?), but the above at least hints at a potential clash between declaring ESCAPE and including the <errno.h> header.
