Tcl Source Code

DJGPP requires special flag O_BINARY in order to not
terminate
reading of file upon encounder of EOF character (\x1F)

There is no provision for this flag in tclUnixChan.c

So,  regardless of configuration option,  -eofchar
(which seems to 
not be handled by DJGPP port at all) file reading is
termintated
upon first \x1F character.

It is possible however to seek after offending
character and read
rest of file.

Tcl commands open/read and file copy are affected

Following patch fixes this problem in quick and dirty
way, adding
O_BINARY to every open call in hope that upper levels
of Tcl
channel code would deal with eol issues.

It seems that for proper filesystem handling DJGPP
environment
shouldn't be treated as "Yet another Unix", because
most of DOS filesystem issues are rather Windows-like.

So, someone of Tcl team at least have taken care of DJGPP port?
I guess that only critical thing which remains to be done to
have djgpp tcl fully functional is exec family of functions.
I have some ideas how to implement as much of tcl exec and
open "|..." functionality as single-tasking OS permits, but
haven't got time to do it.
