Samba idl and warnings in default build

[Steve French]

After noticing a bug slip through because of a compile warning I
didn't notice - I took a look at the normal compile warnings during
Samba build and noticed that Samba is generally pretty clean (although
not as strict as most kernel components) about not having too many
compile warnings, with a few exceptions.   The one area where there
seemed to be huge number ( > 200) warnings - was generating the idl
files.

Any idea why so many warnings in generating the idl in the normal
Samba build (Just tried this on recent Fedora with v4-7-test branch
and hit > 200 idl generation warnings)?  It can make it harder to spot
real bugs in our code (as I just experienced yesterday).
