These are the changes done by the `patches' file:
[These patches have been applied, more or less, so I don't supply the
patches file--law]
Compilation of some portions is done conditional on the definition
of the following symbols:
BINARY Enables the usage of setmode under MSDOS (added binmode command)
BUGGY_MSC Adds #pragma_function(memset) to avoid internal compiler error
CHOWN Enables chown
CHROOT Enables chroot
FORK Enables fork and changes the compilation of system
GETLOGIN Enables getlogin
GETPPID Enables getppid
GROUP Enables all the group access functions
KILL Enables kill
LINK Enables link
PASSWD Enables all the password access functions
PIPE Enables the pipe function
WAIT Enables the wait function
UMASK Enables the umask function
S_IFBLK * Enables the block special device check
S_ISGID * Enables the setgid check
S_ISUID * Enables the setuid check
S_ISVTX * Enables the vtx check
unix * Compiles globbing for Unix
MSDOS * Compiles globbing for MS-DOS
Closes stdaux and stdprn on startup
Adds a copyright message for -v
Disables the compilation of my_popen, my_pclose as the
are in a separate file.
Symbols marked with * are defined in the compilation environment. The
rest should be added to config.h (config.h.SH). All functions when not
supported give a fatal error.
Added documentation for the binmode function in the manual.
Fixed the following bugs:
In eval.c function eval if ioctl or fcntl returned something
other than 0 or -1 the result was a random number as the
double `value' variable wasn't set to `anum'.
In doio.c function do_exec there were two errors associated with
firing up the shell when the execv fails. First argv was not freed,
secondly an attempt was made to start up the shell with the cmd
string that was now cut to pieces for the execv. Also the maxible
possible length of argv was calculated by (s - cmd). Problem was
that s was not pointing to the end of the string, but to the first
non alpha.
[These are incorporated in patches 15 and 16--law]
