Bug ID: 39904
Summary: Show "You must use msvcrt when building in
Unicode/MBCS mode" error only if !defined(__MSVCRT__)
Product: Wine
Version: 1.9.0
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: -unknown

Show "You must use msvcrt when building in Unicode/MBCS mode" error only if
!defined(__MSVCRT__)
Whenever -D_UNICODE is used, running winegcc would give the following error:
../wine-source/include/tchar.h:27:2: error: #error You must use msvcrt when
building in Unicode/MBCS mode
#error You must use msvcrt when building in Unicode/MBCS mode
And as of Wine 1.9.0, adding -mno-cygwin to "use msvcrt" does not make the
error go away.
Fortunately, a solution was suggested by Alexandre Julliard in 2004:

It's not superfluous, but it probably needs a !defined(__MSVCRT__) in
there.

In 2012, Ilya Konstantinov wrote that he successfully overcome that error by
applying Alexandre's change [to tchar.h] locally, see
https://www.winehq.org/pipermail/wine-devel/2012-July/096607.html
I ran into the same problem today, and, as a newbie, spent a long time before I
figured out the proper fix, i.e., to patch tchar.h and to add the -mno-cygwin
flag.
Hence this bug report and the attached patch. Many thanks!
