[Bug-gsl] [bug #36197] reserved identifier violation

[Rhys Ulerich]

Follow-up Comment #1, bug #36197 (project gsl):

I agree that "__GSL_MATH_H_" is problematic according to the link you sent. 
That fix is just a judicious 'perl -pi -e' invocation across the code base and
should be doable.

At a glance, I'm uncertain why "gsl_mode_t" and "gsl_prec_t" tamper with the
POSIX name space.  I see the "ANY header" table entry in the specification you
linked.  It seems the clause "End in the string indicated as a reserved suffix
in the table and do not use the reserved prefixes posix_, POSIX_, or _POSIX_,
as long as the reserved suffix is in that part of the name considered
significant by the implementation." may prevent "gsl_mode_t" from being
problematic, e.g., because it does not have a posix-y prefix.

Regardless, changing the GSL types ending with a "_t" would break the existing
public APIs.  I don't think this part of your report is fixable.
