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
33 # if defined(__MACH__)

37 # include "wx/mac/carbon/config_xcode.h"
41 # define __WXMAC_CARBON__ 1
43 # define __WXMAC_CLASSIC__ 1
49 __WXOSX__ is a common define to wxMac (Carbon) and wxCocoa ports under OS X.
51 #if defined(__WXMAC_OSX__) || defined(__WXCOCOA__)
56 first define Windows symbols if they're not defined on the command line: we
57 can autodetect everything we need if _WIN32 is defined
59 #if defined(__CYGWIN32__) && !defined(__WXMOTIF__) && !defined(__WXGTK__) \
60 && !defined(__WXX11__)
61 /* for Cygwin, default to wxMSW unless otherwise specified */
78 a lot of code (mistakenly) uses #ifdef _WIN32 to either test for
79 Windows or to test for !__WIN16__, so we must define _WIN32 for
80 Win64 as well to ensure that the existing code continues to work.
87 # endif /* !__WIN64__ */

101 The library user may override the default setting of WINVER by defining
102 it in his own makefile or project file -- if it is defined, we don't
105 It makes sense to define WINVER as:
106 - either some lowish value (e.g. 0x0302) to not even compile in the
107 features not available in Windows version lower than some given
109 - or to a higher value than the one used by default for the given
110 compiler if you updated its headers to newer version of Platform
111 SDK, e.g. VC6 ships with 0x0400 headers by default but may also
112 work with 0x0500 headers and beyond
115 # if defined(_MSC_VER) && _MSC_VER < 1300
117 VC6 defines some stuff in its default headers which is normally
118 only present if WINVER >= 0x0500 (FLASHW_XXX constants) which
119 means that our usual tests not involving WINVER sometimes fail
120 with it, hence explicitly define a lower WINVER value for it.
122 # define WINVER 0x0400
123 # elif defined(__DMC__)
125 Digital Mars is distributed with a little outdated headers.
127 # define WINVER 0x0400
130 see MSDN for the description of possible WINVER values, this one
131 is the highest one defined right now (Windows Server 2003) and
132 we use it unless it was explicitly overridden by the user to
133 disable recent features support as we check for all of the
134 features we use which could be not available on earlier Windows
135 systems during run-time anyhow, so there is almost no
136 disadvantage in using it.

215 adjust the Unicode setting: wxUSE_UNICODE should be defined as 0 or 1
216 and is used by wxWidgets, _UNICODE and/or UNICODE may be defined or used by
217 the system headers so bring these settings in sync

262 while the new, standard ones (like <iostream>) do it in std:: namespace
