All C++11 toggles are now removed. What is left is either platform
specific (POSIX_SIGNALS, WINDOWS_SEH), or possibly still needed
(USE_COUNTER).
If current CLion is compatible with `__COUNTER__`, then we should also
force `__COUNTER__` usage.

Should probably do finer grained compiler checking - but this should at least be better than what was there before
When using C++11, comparison operators are already templated to take
anything that can be explicitly converted to double, but constructor
took only doubles. This lead to warnings when an `Approx` was
constructed from floats, which was problematic for some users.
Since just adding float constructor would be a large breaking change, as
suddenly `Approx( 1 )` would become ambiguous, I added a templated
constructor that will take anything that is explicitly convertible to
double. This has the added benefit of allowing constructing `Approx`
instances from instances of strong typedefs, ie allowing
`calculated_temp == Approx( known_temp)`.
Closes#873
Unexpected exceptions no longer cause abort and there should be no more
potential for false negatives.
The trade-off now is that exceptions are no longer translated.
This is another warning that follows test macros, making it painful to
suppress without leaking outside. Luckily clang's `_Pragma`
implementation works.
Should fix#308
Effectively a revert of previous commit, fixing #542, where this was
added to stop linters complaining about `REQUIRE_THROWS_AS` used like
`REQUIRE_THROWS_AS(expr, std::exception);`, which would be slicing the
caught exception. Now it is user's responsibility to pass us proper
exception type.
Closes#833 which wanted to add `typename`, so that the construct works
in a template, but that would not work with MSVC and older GCC's, as
having `typename` outside of a template is allowed only from C++11
onward.
This seems to give about 15% speedup when compiling tests using GCC.
The tradeoff is that under certain circumstances, there is a chance for
false negative result, when the expression under test throws exception
and the test code catches it before it gets to the test runner.
Example:
``` cpp
TEST_CASE("False negative") {
try {
REQUIRE(throws() == "");
} catch (...) {}
}
```
This test case will succeed, reporting no assertions checked, instead of
failing as it would with `CATCH_CONFIG_FAST_COMPILE` disabled. However,
just removing the try-catch block inside client's code will fix this, so
it is worthwhile.
This change does not apply to CHECK* macros, because these are currently
specified as continuing on exception and thus need the local try-catch
to work as intended.
std::ifstream in libstdc++ contains a bug, where it sets errno to zero.
To work around it, we manually save the errno before using std::ifstream
in debugger check, and reset it after we are done.
We also preventively save errno before using sprintf.
Fixes#835
