New description:

 {{{
 There is a BOOST_NO_WREGEX mode in Boost.Regex that
 disables support for wide character regex classes when
 no support is available (either BOOST_NO_CWCHAR,
 BOOST_NO_CWCTYPE or BOOST_NO_STD_WSTRING has to be
 defined). A BOOST_NO_CREGEX mode would be desirable to
 support platforms that define BOOST_NO_ANSI_APIS and
 don't have the necessary C runtime or Win32 functions.
 It would also help when one wants to test if his
 application does use ansi (regex) classes.

 I attached a possible patch that patches the related
 files in boost/regex/, but there would be considerable
 work (I guess) in libs/regex/ to omit using ansi API
 functions.

Comment:
 I'm closing this one, as Boost.Regex now builds on WinCE, which I believe
 was the original issue.
