CATCH_CONFIG_WINDOWS_SEH // Enable SEH handling on Windows
CATCH_CONFIG_FAST_COMPILE // Sacrifices some (extremely minor) features for compilation speed
CATCH_CONFIG_POSIX_SIGNALS // Enable handling POSIX signals
CATCH_CONFIG_WINDOWS_CRTDBG // Enable leak checking using Windows's CRT Debug Heap
Currently Catch enables `CATCH_CONFIG_WINDOWS_SEH` only when compiled with MSVC, because some versions of MinGW do not have the necessary Win32 API support.

`CATCH_CONFIG_POSIX_SIGNALS` is on by default, except when Catch is compiled under `Cygwin`, where it is disabled by default (but can be force-enabled by defining `CATCH_CONFIG_POSIX_SIGNALS`).
`CATCH_CONFIG_WINDOWS_CRTDBG` is off by default. If enabled, Windows's CRT is used to check for memory leaks, and displays them after the tests finish running. _Note that this instrumentation is only done when Catch supplies its own main._
Just as with the C++11 conformance toggles, these toggles can be disabled by using `_NO_` form of the toggle, e.g. `CATCH_CONFIG_NO_WINDOWS_SEH`.
