forward declarations

[Miika Komu]

DB: Forward declarations should hardly ever be necessary, but they are found
all over HIPL.

Are _all_ forward declarations removed by now?

Is there an easy way to grep for forward declarations?

[Diego Biurrun (diego-biurrun)]

The following found one more:

~/src/hipl/trunk $ find . -name \*.c | xargs grep -P -r '^[a-zA-Z0-9]+ .+[a-zA-Z0-9_]+\(.*\);'
./firewall/hslist.c:static SList *slist_last(SList *list);

My idea was to grep for keyword/type at the beginning of the line, then a space, then the function name, some stuff within parentheses and the semicolon. Probably I'm overlooking something, but that should have discovered the most glaring cases.
