dnl FC_CHECK_X_LIB(LIBRARY, FUNCTION [, ACTION-IF-FOUND [,
dnl ACTION-IF-NOT-FOUND]])
dnl
dnl This macro is intended to search for X11-related libraries. It takes the
dnl following variables for input:
dnl X_LIBS -- prefixed to all linker lines
dnl X_EXTRA_LIBS -- suffixed to all linker lines
dnl LIBS -- suffixed to all linker lines (after X_EXTRA_LIBS)
dnl Thus, the trial linker line will be "$X_LIBS -l$1 $X_EXTRA_LIBS $LIBS".
dnl
dnl The following variables are output:
dnl X_EXTRA_LIBS -- contains "-l$1 $X_EXTRA_LIBS" if the link succeeds
dnl
dnl Thus, the intended usage of this macro is something like this:
dnl AC_PATH_XTRA
dnl X_LIBS="$X_LIBS $X_PRE_LIBS"
dnl dnl Is it just me or is AC_PATH_XTRA broken?
