AC_PROG_CPP not quite usable for cross-compiling

[Momchil Velikov]

Hi there,

AC_PROG_CPP and maybe others depend upon the existance of the header
<assert.h>.

This renders it unusable for certain environments, where there are NO
host headers, e.g. a fresh GNU libc port.

Is there any way to work around this and possibly other "sanity"
checks ?

If no, I'd volunteer to remove the offending macros.
