Problem reported by Bruno Haible (sr #110518). * doc/autoconf.texi (Generating Sources) (Running the Preprocessor, Running the Compiler) (Running the Linker, Runtime): Briefly mention that the program snippets are expanded as unquoted here-documents. (Here-Documents): Document escaping needed in unquoted here-documents. Remove mention of \" glitch in OpenBSD 2.7 sh; that old system has not been supported for many years. Remove advice that every \ must be quoted, as that sort of quoting (though harmless) is not needed and is rarely done. * lib/autoconf/c.m4 (AC_C_BIGENDIAN, _AC_LANG_OPENMP(Fortran 77)): * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Properly quote code snippets. The backslash-newline typos were harmless, and the backslash-$ typo has unspecified behavior as per POSIX though the typo is harmless on all shells I know of. However, Autoconf should follow its own quoting advice. |
