This one was probable missed when creating mpconfigport.h, but the underlying code (file.c) gets compiled and works perfectly so no reason to omit it.
This is experimental, community-supported Windows port of MicroPython. It is based on Unix port, and expected to remain so. To cross-compile under Debian/Ubuntu Linux system: sudo apt-get install mingw32 mingw32-binutils mingw32-runtime make CROSS_COMPILE=i586-mingw32msvc- The port requires additional testing, debugging, and patches. Please consider to contribute.
