#
# This is a minimal Make file designed to be called from within a MinGW Cmd prompt.
# So if the distro ZIP file has been unpacked into C:\nodemcu-firmware then 
#
# C:\nodemcu-firmware\app\lua\luac_cross> mingw32-make -f mingw32-makefile.mak
#
# will create the WinX EXE luac.cross.exe within the root C:\nodemcu-firmware folder.
# This make has been stripped down to use the basic non-graphics MinGW32 install and 
# standard Windows commands available at the Cmd> prompt.  This make is quite separate
# from the normal toolchain build.
