Most `configure' scripts use tests supplied with Autoconf as well as other tests
that the package developer wrote or imported from third-party sources. If the
standard tests yield incorrect results when cross-compiling, please let us know
more details. We may be able to fix the problem.

It can be easier to edit `config.h' and Makefile variables directly to get
things working. You can distill the manual changes into `configure.ac'
modifications when finished.
