ChangeLog for previous patch: regenerate intl-auto-encap-win32.c
(fix build problems when building --with-msw=no on Cygwin)
-------------------- ChangeLog entries follow: --------------------
lib-src/ChangeLog addition:
2010-01-15 Ben Wing <ben@xemacs.org>
* make-mswin-unicode.pl:
Various fixes to get this to work when using the Cygwin header files
in /usr/include/w32api instead of the VC++ ones:
-- Use /usr/include/w32api as default; don't assume that a passed-in
directory always ends in .../include.
-- Add `const' to list of known type modifiers.
-- If function already seen, warn but don't generate twice.
-- Eliminate `extern' from return type modifiers.
-- Cosmetic: When eliminating APIENTRY, also eliminate following
whitespace.

Regenerate these files from Cygwin headers.
* intl-encap-win32.c:
Bracket more functions in HAVE_MS_WINDOWS, to fix build problems
when building --with-msw=no on Cygwin.
Fixes for Cygwin headers:
-- Comment out IME.H, non-existent in Cygwin.
-- Make MessageBoxIndirect a `no' (don't encapsulate but generate
error if used) because it has a structure parameter that needs
to be A/W split but is declared as FOO*, and our parser can't
split this.
