minix/lib/nbsd_libminlib/itoa.c
Gianluca Guida 878ba523ac Add libminlib for NBSD libc compilation.
This library includes various random and minix-specific functions
included in the Minix libc. Most of them should be part of libsys,
and in general it would be nice to extinguish this library over
time.
