[patch] typedef'd arrays and functions

[Roger Leigh <roger whinlatter uklinux net>]

Hello,

I'm trying to get gtk-doc to work with Gimp-Print, but it can't cope
with some of the C constructs we use:

1.  Typedef'd arrays:

 		if ($2 !~ m/^struct\s/ && $2 !~ m/^union\s/) {
 #		    print "Found typedef: $_";
 		    &AddSymbolToList (\$list, $3);

This just lets the regex know about arrays, so they don't end up as
part of the symbol name, which is incorrect and also makes broken
SGML.


2. Typedef'd functions.

*  typedef void stpi_ditherfunc_t(int, const unsigned short *, int, int);

This isn't detected at all, even though (AFAIK) it's perfectly valid
C, i.e. a typedef'd *function*, not a function *pointer*.


Regards,
Roger


PS.  I've reposted this now I've subscribed to the list.  The original
seems to be stuck in "moderator limbo".
