Silence signed/unsigned mismatch warning on Cygwin.

Lastique · Lastique · commit b6130f0f17c2 · 2025-12-14T15:29:09.000+03:00
On Cygwin, NTE_BAD_SIGNATURE is defined as HRESULT, which is a signed
integer. This produces a signed/unsigned mismatch warning when it is
compared against a DWORD error code.
