Subject:	symlink() & is_v2_prog() question
Reply-To:	djgpp-workers AT delorie DOT com

Hello,

I got a little bit confused by current symlink() code. The reason -
symlink() uses helper function is_v2_prog(), which returns 1 for
v2 DJGPP program, 0 for any other program and -1 for anything else.
The main symlink() code calls this function to determine the type
of linked file. And my question is - why symlink() code checks
only for return value 0, and does not handle -1 ?

?  /* It is an existing file but no v2 executable */
?  if (v2_prog == 0)
?  {
?    errno = EXDEV;
?    return -1;
?  }

This looks like a bug for me, but before submitting a patch
I'd like to know, haven't I overlooked something? Are there
any reasons for keeping current code, which e.g. executes silently
symlink("c:/io.sys", "c:/test.exe") and produces not working
test.exe file?
