Hi all;

If I try to cross-compile popt 1.14, the configure fails (I'm
cross-compiling for powerpc):

        checking for string.h... (cached) yes
        checking for va_copy() function... configure: error: cannot run test program while cross compiling
        See config.log' for more details.

I worked around this by pre-setting the variable in the environment when
invoking configure:

        ac_cv_va_copy=C99 ./configure ...

It would be nice if cross-compiling were supported.

Cheers!
