Severity: 5 - Medium

Ticket details:
According to https://docs.microsoft.com/en-us/cpp/c-runtime-library/setjmp3
The correct api is int _setjmp3(jmp_buf env, int count, ....) where count is
the number of parameters that follow.
On 32-bit, as of e33afcd864a4e90a7b170585d802a3f85fbe7dfe, the setjmp.h that
got generated, maps setjmp(buf) to _setjmp3(buf, NULL)
I don't know what issue this causes, but as setjmp (_setjmp3()) is returning
-1, it might be an issue.
Also on the same page, _setjmp3 should not be used in a c++ context. The header
setjmp does not prevent _setjmp3 for c++.
There's a define USE_NO_MINGW_SETJMP_TWO_ARGS, which controls the number of
args to setjmp, but I don't know why yet.
