Cross-compiles can be handled at configure time, by using predetermined
test results (and assuming the worst in cases where we the system is not
in our list).

Here's the current matrix:

   1 = checking whether printf supports size specifiers as in C99...
   2 = checking whether printf supports the 'a' and 'A' directives...
   3 = checking whether printf supports the 'n' directive...
   4 = checking whether printf supports POSIX/XSI format strings with 
positions...
   5 = checking for snprintf...
   6 = checking whether snprintf truncates the result as in C99...
   7 = checking whether snprintf returns a byte count as in C99...

   . = yes, # = no.

Volunteers wanted: If you have access to a system with
  - FreeBSD 5.x
  - OpenBSD
  - HP-UX 10
  - Cygwin

could you please run the configure script from the attached package and
report the results?
