I have tried this by inserting -D_POSIX_SOURCE in CFLAGS.  There were other
problems,  the compilation of libfut.a failed after a series of nasty 
warnings and one fatal error.  What I have not tried is to use this flag
only for the compillation of ls.c.

Alexander V. Lukya's <lav AT video DOT yars DOT free DOT net> suggestion to simply erase
the offending line is Alexandrian in its directness.  It works, but leaves
me somehow uneasy.

Compiled this way, with -O2, the fourteen files come in at 860.5 Kb. 
This is an average of 2.5 Kb per file larger than the September compilation.
In the absence of a test suite, the best I can do is use them 'til problems
develop.  Regards, Frank.
