Help with some .xs file modifications

[Gabriel Schulhof]

Hi!

As part of the dialog transience stuff, I need to modify some of the
perl .xs files. I know next to nothing about the syntax. In particular,
I have, in GtkDialogs.xs:

void
pidgin_dialogs_about()

I need to change this to either require a parameter of type GtkWindow *,
or, if the syntax allows it, to be defined thusly and provide a default
value of NULL to the C function.

TIA for your help,



Gabriel
