-----------
[GH #832] Probe for broken snprintf %+..u in mingw and fix it.
snprintf %+u fails on mingw only. t/op/sprintf.t test 217 and
t/op/string.t: 196, 198 (now 197)
The + is always printed, but should not.
As it works okay in win32 (with msvcrt.ll) and cygwin (cygwin1.dll)
on the same system, I assumed it's mingw only snprintf/sprintf wrapper
issue.
Probe in auto:snprintf for PARROT_HAS_BROKEN_SPRINTF_UPLUS and skip
the '+' in %+..u in spf_render.c.
But the probe is not yet correct. It passes on mingw, but should fail.
