I've adapted the configure.in to the new version. configure.in is now called configure.ac, so you should rename configure.in.

Trouble was caused by nested macro calls:

AC_TRY_COMPILE([#define hypot /* */
#include <math.h>],[{}],[],AC_CHECK_FUNCS(hypot))

These have to be quoted

AC_TRY_COMPILE([#define hypot /* */
#include <math.h>],[{}],[],[AC_CHECK_FUNCS(hypot)])

as stated in the autoconf->Programming in M4->M4 Quotation->Quotation and Nested Macros
It took me 4 hours to get to that point. :-(

Thanks for tracking down the problem. I will fix the quoting and have another look at the new version of autoconf.
