[En-Nut-Discussion] Compiler errors on signed/unsigned compares

[Michel Hendriks]

Hi all,

It looks like you missed my remark that the *newer* gcc no longer complains.
The old one *does* complain and so it is fine.

The set of software that no longer complains consists of NutOS 3.9.8.2, GCC
3.3.1 and avr-libc 0.99.90.20030829.

And apparently(?), GCC 4.0 also does not complain as NutOS 3.9.8.2 got
released with pro/dhcpc.c, pro/wins.c and fs/pnutfs.c that have
singed/unsigned issues.

So, the short version: apply my suggested fixes?

Greetings,
Michel

Hi Hendriks

I might ask why you are using some compiler package from 2003.
And specifying the gcc resp. avr-libc version does help more then the
windows package date (I'm not using windows, as you might have guess by
now).

Otherwise gcc 4.0 complaints by default about signed/unsigned compares.
At least it emits warnings, which stop compiling.

So you might try a new compiler if you like and/or start fixing the
signedness issue.
