and if you have cde, dtksh is ksh93 [plus x stuff].  also,
research.att.com now gives ksh93 src and bins away.

ksh88 had a FLOAT compile-time option, off by default because it was
broken.  it was finally fixed in 88i though, but still left off.
other nice but off-by-default options are csh-style BRACEPAT and FS_3D
for nmake-style VIEWPATHing.
