I encountered this issue with a package which sets up rpm.specs for
Cygwin-rpms (rpm.specs for Cygwin require the executables to be
packaged into them with .exe).

Until now this package's configure.in has been using AC_EXEEXT alone
(w/o AC_PROG_CC), now I seem to need adding AC_PROG_CC, but ..
.. autoupdate doesn't diagnose this issue.
.. autoconf doesn't complain
.. Why should one need AC_PROG_CC to a configure.in, if a package
does not require any compiler?
.. Adding AC_CANONICAL_HOST would give sense, but this also
apparently isn't sufficient.
