19 Codewarrior doesn't define any Windows symbols until some headers
28 __WXMAC_CLASSIC__ means ppc non-carbon builds, __WXMAC_CARBON__ means
29 carbon API available (mach or cfm builds) , __WXMAC_OSX__ means mach-o
30 builds, running under 10.2 + only
34 #define __WXMAC_OSX__ 1
35 #define __WXMAC_CARBON__ 1
36 #define __WXMAC_CLASSIC__ 0

53 first define Windows symbols if they're not defined on the command line: we
54 can autodetect everything we need if _WIN32 is defined
56 #if defined(__CYGWIN32__) && !defined(__WXMOTIF__) && !defined(__WXGTK__) \
57 && !defined(__WXX11__)
58 /* for Cygwin, default to wxMSW unless otherwise specified */
75 a lot of code (mistakenly) uses #ifdef _WIN32 to either test for
76 Windows or to test for !__WIN16__, so we must define _WIN32 for
77 Win64 as well to ensure that the existing code continues to work.
84 # endif /* !__WIN64__ */
87 #if (defined(_WIN32) || defined(WIN32) || defined(__NT__) || defined(__WXWINCE__)) \

98 see MSDN for the description of possible WINVER values, this one is the
99 highest one defined right now (Windows Server 2003) and we use it unless
100 it was explicitly overridden by the user to disable recent features
101 support as we check for all of the features we use which could be not
102 available on earlier Windows systems during run-time anyhow, so there is
103 almost no disadvantage in using it.

161 Include wx/setup.h for the Unix platform defines generated by configure and
162 the library compilation options
164 #include "wx/setup.h"
166 /* check the consistency of the settings in setup.h */
167 #include "wx/chkconf.h"
170 adjust the Unicode setting: wxUSE_UNICODE should be defined as 0 or 1
171 and is used by wxWidgets, _UNICODE and/or UNICODE may be defined or used by
172 the system headers so bring these settings in sync
175 /* set wxUSE_UNICODE to 1 if UNICODE or _UNICODE is defined */
176 #if defined(_UNICODE) || defined(UNICODE)

193 #endif /* wxUSE_UNICODE */
195 #if defined( __MWERKS__ ) && !defined(__INTEL__)
196 // otherwise MSL headers bring in WIN32 dependant APIs
200 some compilers don't support iostream.h any longer, while some of theme
201 are not updated with <iostream> yet, so override the users setting here

216 old C++ headers (like <iostream.h>) declare classes in the global namespace
217 while the new, standard ones (like <iostream>) do it in std:: namespace
219 using this macro allows constuctions like "wxSTD iostream" to work in
229 OS: first of all, test for MS-DOS platform. We must do this before testing
230 for Unix, because DJGPP compiler defines __unix__ under MS-DOS
