Hi Arnaud,

I wish it very much, that's why I'm here.
Yes, back in 2005 I was young and idealistic, that's why you finally marked
al175 as 'broken', but now I understand your points and that in NUT you need
good portability.
So this time I've checked everything with
CC="gcc -std=c89 -pedantic", and
CC="gcc -std=c99 -pedantic"
Though I'd like to, but could not use -pedantic-errors, becuase there is a
portablilty problem in drivers/main.h:
main.h|60| error: ISO C90 does not support flexible array members
----
Changes since al175 as recently removed from NUT tree:
- DEBUG macro replaced with runtime debugging switch (using nut_debug_level)
- rechecked http://eu1.networkupstools.org/doc/2.2.0/developers.html and
applied where apporpiate
Also

> reasons (to name a few), it's flagged 'broken' instead.
Yes, at present shutdown is not supported, and unfortunately now I don't have
AL175 hardware at hand, so that I can't write it and verify the implementation.
I've marked the driver as DRV_EXPERIMENTAL, although it was tested by us as
part of our systems to work OK for more than three years in production
environment on ships (and we don't need shutdown there -- in critical
situations the system has to operate as long as possible, untill the battery is
empty)
Also, all of the previous issues listed below are now fixed in this al175
version:
- ‘return’ with a value, in function returning void (2x)
- anonymous variadic macros were introduced in C99
- C++ style comments are not allowed in ISO C90
- ISO C forbids braced-groups within expressions (5x)
- ISO C90 forbids specifying subobject to initialize (16x)
- ISO C99 requires rest arguments to be used (18x)
Yes, "All the world is not an x86 Linux box," and I've tried to make all the
world happy.
Please apply.
> Merry Christmas and happy New Year.

Merry Christmas and happy New Year to you too!
Kirill.
