Message:

Work around Cygwin's crash-suppression behavior

Cygwin calls ::SetErrorMode(SEM_FAILCRITICALERRORS), which any processes it launches will
inherit. This is bad for testing/debugging, as it causes the post-mortem debugger not to be
invoked. (Cygwin does this because it makes crashes more UNIX-y.) We reset the error mode
when our test apps launch to work around Cygwin's behavior.

Fixes <​http://webkit.org/b/55222> Test apps crash silently (without invoking post-mortem
debugger) when launched from Cygwin 1.7

Reviewed by Darin Adler.

Source/JavaScriptCore:

• API/tests/testapi.c: Added a now-needed #include.

(main):

• jsc.cpp:

(main):
Call ::SetErrorMode(0) to undo Cygwin's folly.

• JavaScriptCore.vcproj/testapi/testapiCommon.vsprops: Define NOMINMAX like many of our

other projects do so that windows.h won't define min/max macros that interfere with
std::numeric_limits<T>::min/max.

Tools:

• DumpRenderTree/win/DumpRenderTree.cpp:

(main):

• TestWebKitAPI/win/main.cpp:

(main):

• WebKitAPITest/main.cpp:

(main):

• WebKitTestRunner/win/TestControllerWin.cpp:

(WTR::TestController::platformInitialize):
Call ::SetErrorMode(0) to undo Cygwin's folly.
