Why are you using both -mconsole and -mwindows?  Don't they contradict
each other?

These look like either missing import libraries on the link command
line, or maybe some snafu with including windows.h, which declares
these functions.  The former problem could have been caused by the
fact that you used both -mconsole and -mwindows.  I suggest to add -v
to the GCC command line and see which libraries it scans.
