(make_hdr) [MSDOS]: If a_name is a coff-go32-exe executable with a
prepended stub, compute coff_offset.
(make_hdr, copy_sym) [COFF]: Use coff_offset when seeking into temacs.
(O_RDONLY, O_RDWR): Define if undefined.
[emacs] (report_error): Use report_file_error so the user can tell what the
errno code was.
(unexec): Use O_RDONLY instead of explicit 0.
(make_hdr): Don't undo A_TEXT_OFFSET adjustment #ifndef NO_REMAP, since it
was never adjusted earlier #ifndef NO_REMAP.
(adjust_lnnoptrs): Use O_RDWR instead of explicit 2.
and debugger. Use the <coff.h> that was put in the right place
a couple of djgpp versions ago. Consequently, use `unsigned short'
for `word16' and `unsigned long' for `word32'.
(make_hdr) [MSDOS]: Cast a pointer for bzero.
(write_segment) [EFAULT]: Check for before using.
(adjust_lnnoptrs) [MSDOS]: Use provided descriptor.
(adjust_lnnoptrs): Return 0 if ok.
* s/template.h: Mention that you should #define HAVE_TERMIO or
HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
tcsetpgrp to *pgid; it's just a status value.
* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
systems using XFree386, and perhaps is inappropriate in general.
* m/intel386.h: #undefine the integer size macros, since the Linux
<values.h> file #defines them itself.
* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
fails, fall back on ULIMIT_BREAK_VALUE.
* process.c: Linux needs the WAITTYPE, etc. definitions.
* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
no need to use SYSV names.
* s/linux.h: New file.
