(gl_UNKNOWN_WARNINGS_ARE_ERRORS(C)): New macro. (gl_UNKNOWN_WARNINGS_ARE_ERRORS(C++)): New macro. (gl_UNKNOWN_WARNINGS_ARE_ERRORS): Dispatch to gl_UNKNOWN_WARNINGS_ARE_ERRORS(_AC_LANG). (gl_WARN_ADD): Require the gl_UNKNOWN_WARNINGS_ARE_ERRORS specialization of the current language. If C++ is the current language, modify WARN_CXXFLAGS instead of WARN_CFLAGS. * manywarnings.m4 (gl_MANYWARN_ALL_GCC(C)): New macro, extracted from gl_MANYWARN_ALL_GCC. (gl_MANYWARN_ALL_GCC): Dispatch to gl_MANYWARN_ALL_GCC(_AC_LANG).
