catch(...) is used in Win32/Signals.inc for catching Win32 structured exceptions, but according to [1], this is wrong. We can't simply change try/catch to __try/__finally, since this syntax is not supported by MinGW. We can use __try/__finally on MSVC and __try1/__except1 macros on MinGW [2], but I think that that solution obfuscates the code too much. The use of try/catch(...) in Signals.inc makes it impossible to link MinGW-compiled libSystem with llvm-gcc compiled executables. I propose that we just remove try/catch(...) from Signals.inc, since the meaning of the code won't change.
