* src/scan-code.l (show_sub_message):
Redo initializations to work around a bogus Sun C 5.12 warning.
(parse_ref): Remove unreachable code that Sun C 5.12 complains about.
* src/uniqstr.h (uniqstr_vsprintf): Use
_GL_ATTRIBUTE_FORMAT_PRINTF (...) instead of __attribute__
((__format__ (__printf__, ...))). Otherwise, Sun C 5.12
complains about an unknown attribute.
Improve the output by ensuring a well defined order for type switches.
* src/uniqstr.h: Style changes for macro arguments.
(UNIQSTR_CMP): Replace by...
(uniqstr_cmp): this.
* src/uniqstr.c (uniqstr_cmp): New.
Produce well defined results.
* src/output.c: Use it.
Fix the following warning
parse-gram.c:2078:14: error: equality comparison with extraneous parentheses
[-Werror,-Wparentheses-equality]
if (((yyn) == (-91)))
~~~~~~^~~~~~~~
parse-gram.c:2078:14: note: remove extraneous parentheses around the
comparison to silence this warning
if (((yyn) == (-91)))
~ ^ ~
parse-gram.c:2078:14: note: use '=' to turn this equality comparison into
an assignment

This is Apple clang version 3.1 (tags/Apple/clang-318.0.61).
* data/c.m4 (b4_table_value_equals): Use (!!(A == B)) instead of (A == B)
to avoid this warning.
Any reasonable compiler should generate the same code.
* src/uniqstr.h (UNIQSTR_EQ): Likewise.
* data/glr.c (LONGJMP): abort after longjmp to pacify clang.
