George and I talked more off-list / phone and he convinced me that it's ok to do this in a top-level header file:

#if defined(c_plusplus) || defined(__cplusplus)
#undef restrict
#define restrict
#endif

I'll post to the Autoconf list about this soon.

Hi,

I am pretty sure that C++ has no restrict keyword (only C99), so IMHO
it's not the compilers fault is not compiling.
You probably want to turn restricts off for C++ by default, unless you
know the compiler supports it.

best regards,
Samuel
