#serial 2
dnl A replacement for autoconf's macro by the same name. This version
dnl uses `ac_lib' rather than `i' for the loop variable, but more importantly
dnl moves the ACTION-IF-FOUND ($3) into the inner `if'-block so that it is
dnl run only if one of the listed libraries ends up being used (and not in
dnl the `none required' case.
dnl I hope it's only temporary while we wait for that version to be fixed.
undefine([AC_SEARCH_LIBS])
dnl AC_SEARCH_LIBS(FUNCTION, SEARCH-LIBS [, ACTION-IF-FOUND
dnl [, ACTION-IF-NOT-FOUND [, OTHER-LIBRARIES]]])
dnl Search for a library defining FUNC, if it's not already available.
