This arch specific code made me look into this detail, and it looks like 
wine's msvcrt.spec has got it slightly wrong.

The current file has got this:
@ cdecl -arch=win32 __p__fmode() MSVCRT___p__fmode

While mingw-w64's def files only provides this function for i386, not for 
armv7. I checked with an actual arm32 msvcrt.dll, and that matches 
mingw-w64's def file, i.e. __p__fmode only exists on i386.
