MSCLOCKS_PER_SEC is no longer hard-coded to 1000 on non-*nix platforms
("ms" stands for "Microsoft", not "milliseconds").
Added comment with example (floating point) values for MSCLOCKS_PER_SEC
on non-*nix platforms.

(Borland defines CLOCKS_PER_SEC as 1000.0).
Added msclock_t definition (currently always the same as clock_t).

the correct implementation of ctime_r() to be used.

implementations... one with three args which is from a draft standard and
is supplied for backwards compatability, and one with two args which
conforms to the final POSIX standard.

This is a kludge since it doesn't use the correct methods for selecting
which ctime_r() (and asctime_r()) implementation to use.  I don't have time
right now to dig up the "right" way.

Instructions are welcome.  :-)

Added support for the (non-standard) \e = 0x1b escape sequence.
Created the c_escape_* counter-part functions.
