Making yacc tables shared in ccom
The file /usr/src/cmd/pcc/:yyfix is supposed to write a given set of
yacc's tables into the file rodata.c, replacing them with external
declarations in y.tab.c.  In fact, it writes only the last of them
into rodata.c, and reads the rest back into y.tab.c.  Replace :yyfix
with the following, recompile, and about 4Kb of tables become shared.

>rodata.c
for i in $*
do ed - y.tab.c <<! A+1, \1 ! DONE A+1,'BW Q W /^\(.*\)$I[ .-1KA BD /}/KB $I ]*\[]/S//EXTERN </PRE []/ $I[];\\ RODATA.C AR RODATA.C
