20 dnl The cross compile concepts from GNU autoconf are not usable.
21 dnl We permit to execute test programs on a remote machine while
22 dnl running "configure" in a cross compile environment.
23 AC_PROG_CC dnl now check for cross compiling
24 dnl cross_compiling=remote dnl disable GNU cross compile "defaults"
25 dnl rmtcall="$CONFIG_RMTCALL" dnl enable script for remote execution
26 dnl remote execution of test programs may be set up with:
27 dnl CONFIG_RMTCALL=script-path
28 dnl and
29 dnl CONFIG_RMTHOST=host or CONFIG_RMTHOST=user@host
30 dnl If AC_PROG_CC detects a cross compiler and CONFIG_RMTCALL is set, then
31 dnl all test programs are automatically transferred to the test machine
32 dnl and run on that machine.
