/*  Patch 7, February 16, 2023

 *      4e0a1e04 from NetHack-3.7)
 *  avoid potential buffer overflow in append_str()
 *  resolve missing dependency in NetHack.sln
 *  code in include/tradstdc.h was trying to suppress warn_unused result by
 *      defining warn_unused_result to an empty string and that began causing
 *  a build error within a system-supplied header file cdefs.h when using
 *      ubuntu impish 21.10; disable that for any Linux unless GCC_URWARN is
 *      defined to force it back into effect
 *  update_inventory() after leash goes slack
 *  player assigned name for monsters, specific objects, or object types could be
        longer than what was intented to be allowed; for 'curses', much longer
 *  windows: added winflexbison to travis-ci configuration to permit full build of
 *      levcomp and dgncomp
 *  windows: a bad chdir specified in win/win32/dgnstuff.mak caused full build to
 *      abort
 *  windows: the console.rc file had outdated information stating 3.6.3 when the
 *      official 3.6.6 binary was built.
 *  windows: switch from using keyhandling dll's to incorporating the three 
 *      variations (default, ray, 340) in sys/winnt/nttty.c
 *  curses: cherry-picked selectsaved code from 3.7 for menu of save files
 *  NetHackW: fix delayed rendering of cursor when using farlook
 */

/*  Patch 6, March 8, 2020
 *
 *  invalid status highlight color could be maliciously used to corrupt memory
 *  formatting corpse names used internal buffers differently from formatting
 *      other objects and could potentially clobber memory
 *  avoid divide by 0 crash if 'bogusmon' (file of bogus monster types) is empty
 *  avoid #wizrumorcheck crash if either 'rumors.tru' or 'rumors.fal' or both
 *      were empty when makedefs built 'rumors'
 */

 *
 *  fix accessing mons[-1] when trying to gate in a non-valid demon

 *  ensure existing callers of string_for_opt() check return value before using it
 *  fix potential buffer overflow in add_menu_coloring()
 *  fix potential buffer overflow in sym_val()
 *  fix potential buffer overflow in pline(), raw_printf(), and config_error_add()
 *  fix potential buffer overflow in choose_windows()
 *  use vsnprintf instead of vsprintf in pline.c where possible
 *  Windows: incldues a fix from a 3.6.4 post-release update where 
 *      OPTIONS=map_mode:fit_to_screen could cause a game start failure
 *  Windows: users with C-locale unmappable names could get game start failure

 *      trap
 *  allow teleporting onto the vibrating square
 *  message "your knapsack can't accomodate any more items" when picking stuff
 *      up or removing such from container was inaccurate if there was some
 *      gold pending; vary the message rather than add more convoluted pickup
 *      code
 *  dozen-ish assorted spelling/typo fixes in messages and source comments
 *  wizard mode wishing for terrain would leave it unmapped if done while blind
 *  wizard mode terrain wish could leave hero in water (severe vision limits)
 *      or in lava (trapped, sinking) which wasn't there any more
 *  flying hero can go down (via '>') holes or trap doors instead of escaping
 *      trap
 *  polymorphed hero hiding on the ceiling can now use '>' to unhide instead of
 *      being told "you can't go down here"
 *  fix compilation on platforms that split the ncurses and tinfo libraries

 *      option 'portable_device_paths'
