Not-really-cross-compilation issues

[Peter Eisentraut]

I've created a simple shared library that I placed at a non-standard
location for illustration purposes.  Imagine I want to configure a package
to link against that library:

$ cat configure.in
AC_INIT(.)

AC_PROG_CC

AC_OUTPUT

# With Autoconf 2.13:

$ LIBS='-L/tmp/obscure -ltest' ./configure
creating cache ./config.cache
checking for gcc... gcc
checking whether the C compiler (gcc  ) works... yes
checking whether the C compiler (gcc  ) is a cross-compiler... yes
checking whether we are using GNU C... yes
checking whether gcc accepts -g... yes
updating cache ./config.cache
creating ./config.status

(everything okay)

# With Autoconf 2.50-to-be:

$ LIBS='-L/tmp/obscure -ltest' ./configure
checking for gcc... gcc
checking whether the C compiler works... configure: error: cannot run C 
compiled programs.
To enable cross compilation, use `--host'.

This is pretty silly.
