Where is struct tchars defined?

[Jonathon Sivier]

    I am attempting to compile MicroEmacs 3.10 on an IRIS 3020.  I have had to
modify several of the include directives so that the header files will be
looked for under /usr/include/bsd.  In unix.c there is a structure called
tchars used.  It seems to be a set of character strings for a terminal
definition.  I can't find which header file it is in.  Does anyone know where
this structure is defined on the IRIS or failing that what the definition
should be?

    Thanks for your assistance.

    Jonathan
