You seem to be confused and are outsmarting yourself ;) limits.h is a POSIX header. On linux it is supplied by GCC. So if you want to check for "limits", you should use AC_CHECK_HEADERS([limits]) If this fails, something else is broken and you will have to investigate. It could be a bug inside of "limits", it could be problem elsewhere inside of your configure script, or could be a problem with your include paths. It's hard to guess what actually goes wrong without having seen your code. Ralf
