Commit c52f1eb09901e038ceb7012730e7cf3395d65a78 incorectly stated that
_strtoi64 and _strtoui64 symbols are available since the first release of
msvcrt.dll library (part of MS Visual C++ 4.2).
But only the symbol _atoi64 mentioned in that commit is available since
the first msvcrt.dll release.
Symbols _strtoi64 and _strtoui64 (as can be now seen in msvcrt.def.in
comments) were introduced in Windows XP version of msvcrt.dll.
So for I386 msvcrt.dll builds, use mingw-w64 implementation of _strtoi64
and _strtoui64 functions, like it was before that mentioned commit.
The mentioned commit broke support for Windows NT 4.0 and Windows 2000 as
msvcrt!_strtoi64 and msvcrt!_strtoui64 symbols are not available on these
systems.
This issue was reported by Marius Negruțiu into mingw-w64 bug tracker:
