Patch files (named "patch.arc", "tc2pat.arc", and "td1pat.arc") have
been circulating which fix a number of bugs in early "releases" of the
Turbo C 2.0 package.  Later "releases" were patched by Borland.
Unfortunately, the "release" number (2.0) does not indicate which
patches have been applied.  The bugs are in stat(), printf(), td386.exe,
tdh386.sys, and tlib.exe.  The printf() bug is exactly the one which
Robert Seals writes about.

I'll send the patch files to those who send me e-mail.
