Last change on this file since 55f068c was 55f068c, checked in by Jiří Zárevúcky <zarevucky.jiri@…>, 8 years ago

Rename setjmp function to setjmp, use _Noreturn instead of attribute((noreturn)), minor comment changes.

Renaming for consistency with longjmp, and to better express that the implementation
of
setjmp has additional properties not defined by the C standard.
