Reliance on <config.h>

[Ludovic Courtès]

Hi,

I just noticed that Gnulib modules rely on the availability of a
`#include'able <config.h> file.

I'm using Gnulib in a project that does:

  AC_CONFIG_HEADER([some-special-name.h])

There, Gnulib modules fail to compile because <config.h> is not
available.  I'd happily work around this by doing something like:

  AC_CONFIG_HEADERS([some-special-name.h lib/config.h])

but then `autoheader' does not generate `lib/config.h.in', which is a
pain.

Any hint?

Thanks,
Ludovic.
