I am using GhostScript 1.3 with the patches supplied by Tony Li and
snoopy's fix to interp.c.  My platform is an 8MB Sun 3/50 running
SunOS 3.5.  I am compiling with GCC 1.35.

Tracing, at least as implemented in GhostScript, does not work in
UNIX, and the C compilers don't produce map files, so the function
tracing code in gsmain.c is irrelevant.  This is an irritation because
every time I start up GhostScript I get the message

    Unable to find _main in map file

which is confusing.  So I got rid of it by conditionally compiling the
map file code for __MSDOS__.
