I would have expected that this should only influency inlcude like 
"gsl/gsl_include.h" and not <gsl/gsl_inlcude.h>. But anyway...

locale_t is a POSIX-typedef define in GNU C in xlocale.h. 
parser.y includes locale.h that includes xlocale.h. Don't you have something 
like typedef __locale_t locale_t; in your xlocale.h?

Other errors related to the variable locale should disappear once this problem 
is solved.
