But what if I want to achieve something like AC_DEFUN([CX_COMPILER_CHECKS], [CX_STATUS([compiler checks]) AC_PROG_CC AM_PROG_CC_C_O ... ]) where I can't AC_REQUIRE([CX_STATUS]), because that is supposed to be used several times, obviously, and also I need to do stuff between AC_PROG_CC and AM_PROG_CC_C_O (e.g.: store the value of $CC for later use with AM_PROG_AS)? Do I have to move away from AC_DEFUNing CX_COMPILER_CHECKS and to just m4_include'ing the file in question (would be very ugly) to serialize? > Post your configure.ac, if the guess is not right. Good thing I don't have to do that. It's a mere couple thousand lines, but the m4_included files make up for another 8000, not including libtool.m4 (which of course also comes into play).
