Please note that AC_REQUIRE does not operate the way this change makes people believe. It causes the text of AC_C_INLINE to be expanded *before* the beginning of the expansion of gl_HEADER_SYS_SOCKET. Even if that is clear to you now, it will confuse others reading your code. That confusion is lessened if you stick to listing AC_REQUIRE stanzas at the very beginning of macro definitions, outside of any shell conditional statements. Cheers, Ralf
