We can't assume that the number of arguments we get from GetCommandLine
will match what we have from argc, as the former is not wildcard
expanded on MingGW.
mingw64 will ask __getmainargs to expand wildcards depending on
the mingw-specific variable _dowildcard. By default this is set
to 0 (false), but some mingw64-packagers (msys2, mingw-builds)
pass --enable-wildcard during build, changing this default. As
a result, the arguments we get through argc/__argc have already
been expanded. MinGW does not reflect this through GetCommandLine
though, like MSVC does, which triggered the assert.
Amends dff18b8e80.
