Commit 1bd7b2c7 authored by Richard M. Stallman's avatar Richard M. Stallman

[MSDOS]: If DJGPP version 2, include fcntl.h.

(_crt0_startup_flags): Initialize it.
(internal_terminal_init): Change handling of EMACSCOLORS.
(init_environment): Call tzset, not init_gettimeofday.
(ctrl_break_vector, ctrl_break_regs): Don't define if DJGPP v2.
(ctrl_break_func, install_ctrl_break_check): Don't define if DJGPP v2.
(dos_ttraw) [DJGPP v2]: Don't call install_ctrl_break_check.
Call setmode at the end and exit.
(dos_ttcooked): Call setmode at the end and exit.
(gethostname, gettimeofday): Don't define if DJGPP v2.
(alarm, fork, kill, nicr, pause, sigsetask): Don't define if DJGPP v2.
