Actually, that was missing a few (multi-line declarations, signal(3),
which is quite weird, and asm()). The following seems to be complete
(per the count of ';'):
$ cat stdc89
#!/bin/sh
sed -n '/A.3 LIBRARY SUMMARY/,$p' <c89-draft.txt \
| pcregrep -M "(?s)\b$1 *\([[:alnum:]*,._\s\(\)-]*\);$";
$ ./stdc89 '[[:alpha:]][[:alnum:]_]+' \
| grep ';' \
| wc -l
146
$ sed -n '/A.3 LIBRARY SUMMARY/,$p' <c89-draft.txt \
| grep ' .*);' \
| wc -l
146
