I disagree with the characterization of Microsoft C as "very Unix
compatible"; I find it quite lacking, particularly in the library.
Watcom C 8.0 is better, for example it DOES have opendir/readdir.
But more in general, you are right.  Fortunately, "Unix-specific"
library routines ARE becoming easier and easier to find, both built
in to compilers' libraries and in such places as the freed BSD sources
and various freely redistributable programs around the net...
