pthreads-win32 uses exceptions to implement thread cancellation.  This means
that, in the threads that you create, if your code (or any code you call)
uses catch(...), it may inadvertantly circumvent this thread cancellation
mechanism.  This is why there is a warning telling you to use PtW32CatchAll
in place of catch(...).

If you look at the bottom of pthread.h, you will see that PtW32CatchAll is
defined as follows:

#define PtW32CatchAll \
        catch( ptw32_exception & ) { throw; } \
        catch( ... )
