[Plplot-devel] problem with x01c.c

[Andrew R. <ar...@ge...>]

Hello,
    I was doing a final check of the CVS on DOS before heading away for a
week, and found a small problem with x01c.c 

Starting line 8 it has:

#if HAVE_UNISTD_H
# include <unistd.h>
#endif

Under DJGPP and gcc version 2.7.2.1 I get an error with the first line.
Changing it to:

#ifdef HAVE_UNISTD_H
# include <unistd.h>
#endif


fixes the problem at least for me. I don't understand why it was only #if
in the first place, since that should (by my read) be illegal. Perhaps
later version of GCC support it ? Either way, i believe it should be an
#ifdef, not an #if. I have not made the change to the CVS in case it is
doing something I don't understand.
