I was not able to find the symbols in libc.a after I installed the 
Darwin static c library (Libc).  I also ran configure with the TERMIO 
directive.

I successfully installed the Darwin static c library (Libc), and I still 
get the gtty & stty errors.  Apparently, gtty and stty have been made 
obsolete by ioctl().

I quote Cornell's web page:

"______
These subroutines have been made obsolete by the ioctl subroutine.

The stty subroutine sets the state of the terminal associated with the 
FileDescriptor parameter. The gtty subroutine retrieves the state of the 
terminal associated with FileDescriptor. To set the state of a terminal, 
the calling process must have write permission.

Use of the stty subroutine is equivalent to the ioctl (FileDescriptor, 
TIOSETP, Buffer) subroutine, while use of the gtty subroutine is 
equivalent to the ioctl (FileDescriptor, TIOGETP, Buffer) subroutine.

stty.htm


So should I try and replace the calls myself, or would someone be 
willing to help?  An ideal simple test module that has this problem it 
d.colors.

BTW:  pre1 compiled well for me, these are the main modules that 
failed.  So if we can kick this one in the butt, Grass will be nearly 
100% complete on Mac OS X.
