Describe the bug
Error when compiling UsageTests/Misc.tests.cpp:517:5 with MinGW

error: expected 'catch' before '__except'
  517 |     __except (1)

Expected behavior
Compilation with error.

Reproduction steps
Steps to reproduce the bug.
Using MinGW (tested on Fedora) run the following command inside the build directory

cmake .. -DCMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++ -DCMAKE_BUILD_TYPE=Debug -DCATCH_DEVELOPMENT_BUILD=ON
cmake --build . --target SelfTest

Platform information:

  • OS: Fedora 36
  • Compiler+version: x86_64-w64-mingw32-g++ (GCC) 11.2.1 20211019 (Fedora MinGW 11.2.1-5.fc36)
  • Catch version: v3.0.1

Additional context
On first reading the function throw_and_catch() defined in tests/SelfTest/UsageTests/Misc.tests.cpp is used to test SEH on windows. The section is enabled using CATCH_PLATFORM_WINDOWS which includes MinGW. Maybe disable this section for MinGW?

Only test SEH handling with MSVC

MinGW doesn't support `__try` and friends at all, while Clang
only supports it partially, and the test would require some
changes to make it work there. Since this is only a test, we can
afford to keep it MSVC-only.

Closes #2447
