I think that it's not a bug, this is a definition of cross-compiling. If you compiling on a broken system but you expect the resulting executable to run on a "good" system, you are cross-compiling. If you are compling on FreeBSD for Linux and you have iBCS with Linux emulation, you are not cross-compiling. Essentially, if you are cross-compiling, you cannot and should not run executables produced by the build process on the machine doing the build. Autoconf is consistent in this definition. Tests that require compiled programs to be executed are not run as long as a trivial program fails to run. Regards, Pavel Roskin
