This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.1.1 (i386-msvc-nt5.0.2195)
 of 2001-10-22 on buffy
configured using `configure --with-msvc (12.00)'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Keywords appearing with "//"-style comments are being highlighed.
Place the following C-snippet inside a c-mode buffer, and then
font-lock-fontify-buffer it; when I do this, the words "for" and "do"
are (erroneously) highlighted.  In contrast, in the "/* */"-style
comment, keywords are left undistinguished.

void main(void) {
  // keywords appearing within "//" style comments, 
  // like: for do, appear (erroneously) highlighted.

  /* keywords appearing within "/*" style comments,
   * like:  while if, are not highlighted.
   */
}
