You need to show us your configure arguments to be sure. I bet
you're specifying just --host.
I don't know exactly what to do about this. It's caused by:
if test ${build} != ${host}; then
some defaults
else
AC_PROG_CC
fi
AC_TRY_COMPILE
ac_objext is set at the expansion of AC_PROG_CC and if you take the if
branch, it never gets set.
Does anyone reading this know what the right thing to do is? Is there
anything in the autoconf documentation about not using some macros
inside conditional statements?
