# The awk program cvt will convert the relatively sterotyped ansi c
# in this troff distribution into older-style c, by munging function
# declarations.
# You will also have to edit fns.h, by
# sed 's/(.*)/()/g' fns.h >foo; mv foo fns.h
# check this before doing the move!
# you will also have to make some editing changes in
# tdef.h in the Contab structure: s/(void)/()/
# you may have to fix up some function declarations
# in n4.c, the ones with (*f)(Tchar).
# you will surely also have header files to deal with.
# the most obvious cases are dealt with by the following
# commands. make sure you do this stuff on a copy!
# function prototypes in n8.c probably belong in fns.h. readpats(void) must
# be readpats() before cvt runs.
