33 ?X: This unit produces a shell script called Cppsym, which can be used to
34 ?X: determine whether any in a list of symbols is defined by the C compilation
35 ?X: chain (C preprocessor symbols plus C compiler native ones).
36 ?X: It can determine the status of any symbol, though the symbols in $al
37 ?X: are more easily determined. If you want to add to $al you can do
39 ?MAKE:Cppsym ccsymbols cppsymbols cppccsymbols: run \
40 eunicefix Guess awk cat tr sed sort rm rm_try startsh osname \
41 +cc +gccversion test comm uniq echo Options trnl \
42 optimize ccflags ldflags libs cpp_stuff
43 ?MAKE: -pick add $@ %<
44 ?T:also symbols i postprocess_cc_v tHdrH
46 ?X: The symbol list is in alpha order for ease of maintenance...
48 ?X: Lots of new symbols (mostly rummaged from gcc), courtesy of
49 ?X: Jarkko Hietaniemi <jhi@snakemail.hut.fi> -- RAM, 06/06/94
52 ?S: The variable contains the symbols defined by the C compiler alone.
53 ?S: The symbols defined by cpp or by cc when it calls cpp are not in
54 ?S: this list, see cppsymbols and cppccsymbols.
55 ?S: The list is a space-separated list of symbol=value tokens.
58 ?S: The variable contains the symbols defined by the C preprocessor
59 ?S: alone. The symbols defined by cc or by cc when it calls cpp are
60 ?S: not in this list, see ccsymbols and cppccsymbols.
61 ?S: The list is a space-separated list of symbol=value tokens.

65 ?S: when it calls cpp. The symbols defined by the cc alone or cpp
66 ?S: alone are not in this list, see ccsymbols and cppsymbols.
67 ?S: The list is a space-separated list of symbol=value tokens.
85 $echo "Guessing which symbols your C compiler and preprocessor define..." >&4
86 ?X: If your symbol is mixed case, just add it as-is.
87 ?X: All symbols will be transformed to both all-lower and all-upper.
88 ?X: Also drop any leading/trailing underscores, the scan will try all those.
