The C compiler modifications here given as diffs will change a phototypesetter
C compiler to have a larger symbol table (change to c0.h) and to generate
switch code in I space (c11.c).  We install the changed C compiler as
-t0 and -t1; see the source for cc.c.  You need make a modified C compiler
only if you intend to recompile ex (-t0) or if you wish to compile with
smaller data spaces per user; all code will work fine without -t1, and
all programs but ex will compile with normal symbol table size.
