# Automake-1.10's AM_ENABLE_MULTILIB is buggy - it # does not properly preserve quoting when copying # ac_configure_args to the 'config.status' it creates. # I guess one level of quoting is removed when the # copying happens (by means of a 'here'-document in # AC_OUTPUT_COMMANDS). # # Note that we cannot use a different name since # automake 'knows' about AM_ENABLE_MULTILIB and # behaves differently if we would, e.g., name the # modified macro 'MY_ENABLE_MULTILIB'. # Hence we hope that we can override automake/aclocal's # definition. # # Below (look at the 'sed' code) we replace all occurrences # of '$' by '\$' so that 'config.status' again says '$'. # # This is important if we want to pass e.g., # # --exec-prefix='${prefix}/xxx' # # correctly to the multisubdir configurations. # # AM_ENABLE_MULTILIB([MAKEFILE], [REL-TO-TOP-SRCDIR]) # --------------------------------------------------- # Add --enable-multilib to configure.
