'sz' is the size of the buffer; 'if (count < sz) buf[count++] = c;'
can fill the entire buffer, leaving count==sz, so buf[count] = '\0';
would be out of bounds.
Formatting was way off. Indentation these days should be multiples
of 4 spaces, never tabs.
Check that player level is valid before checking if it is rogue.
Prevent attempting to pick a font that is too small.
Don't leak fonts when trying to find a font that fits.

Because multiple window ports are supported on Windows
now, even in the same executable and selectable via
config file in some cases, some adjustments became
necessary. There will likely be some further refining
of this over the next day or two.
List of changes:
Move Windows startup from sys/share/pcmain.c and
into its own sys/winnt/windmain.c so that it can
be modified to fix some current breakage, and
allow altering the order of some things.
There is startup processing code that is common to
all of the Windows WindowPorts, but that startup
processing code needs to have no dependency on
any one of those WindowPorts.
Yet, during startup processing, some of the initialization
routines can end up calling NetHack functions that
expect an active Window port underneath, and if there
isn't one, routines like pline, impossible, panic can
end up invoking null function pointers.
Place a new file sys/share/safeproc.c, in which a complete
window port is available for early startup processing
purposes. It's WindowPort name field is set to
"safe-startup" just for reference. The prototypes in
include/winprocs.h require that SAFEPROCS be
Usage:
windowprocs = get_safe_procs(0);
initializes a set of winprocs function pointers that ensure
none of the function pointers are left null, but that's all it does.
windowprocs = get_safe_procs(1);
initializes a set of winprocs functions pointers that ensure
none of the function pointers are left null, but also
provides some basic output and input functionality using nothing
other than C stdio routines (no platform or OS specific code).
The conditional code related to WIN32 has been removed from
sys/share/pcmain.c
The code common to all of the Windows WindowPorts calls
get_safe_procs() almost immediately to ensure that
there is a set of WindowPort winprocs available.
Still not quite there yet though.
Focusing on tty (maybe curses) right now.
The gui has had significant code deviation from
prior gcc builds for windows and will take more
work.
There are two ways to enable curses in the build. Either set the
environment variable PDCURSES to a folder containing a PDCurses repository
OR place the PDCurses folder alongside the NetHack source repository.
Map back buffer work is done eliminating all flickering caused by
clears of the front buffer during partial updates.
Implemented a cursor blink in both ascii and tile modes.
Fixed bug where we would lose fit to screen when entering rogue level.
appropriately.
Renamed ntassert to nhassert. (Naming mistake caused by using ntassert
at work).
Re-ordered a few more includes to get window headers included before
nethack headers.
Moved the code page 437 mapping table to winnt.c so that it could be
used in window and console clients.
Added check that fonts support unicode values we use from code page 437.
Use unicode to draw text if font supports it otherwise use ASCII.
