Hello all,
I'm building the latest version of avra with lcc-win32
(http://www.cs.virginia.edu/~lcc-win32/) and compiler emits a couple of
warnings:
== cut==
avra.c:
Warning c:\work\avra\avra.c: args.h: 68 Repeated use of const
Warning avra.c: 82 Repeated use of const
Warning avra.c: 150 Missing prototype for 'list_devices'
args.c:
Warning c:\work\avra\args.c: args.h: 68 Repeated use of const
Warning args.c: 55 Repeated use of const
Warning args.c: 69 Repeated use of const
== cut ==
The "missing prototype" one is easy to fix: the declaration of
list_devices in device.h should be changed to "void list_devices(void)".
The second warning is related to the dataset structure which is
referenced in several places as "const struct dataset const *foo". I
can't really figure out what this declaration is supposed to mean, but
my guess is that the first "const" declares every field of the structure
unassignable, while the second "const" declares the referenced structure
itself unassignable, is that right? Shouldn't a single "const" be
sufficient in this case?
I could of course just ignore the second warning, but it would be nice
to get rid of it.
The fix for the first warning is attached to this post.
