Your package fails to build with GCC 4.3. Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning.
You can reproduce this problem with gcc-4.3 or gcc-snapshot from
unstable.

Remove the bit-field and it will work.
Hi, Martin, Debian people, and Recode pre-testers.
This should be corrected for the next release of Recode. Thanks!
Instead of removing the bit-field, I reduced it from 2 to 1, as there
are other bool fields having 1 as a bit field in the same file, and this
does not apparently generate recent problems from other testers.
But I'm pretty sure that if I once used 2 instead of 1, it came from the
fact, when bool is not available and rather made an enum of 0 and 1,
that some compiler (I do not remember which) saw 0 and 1 as signed
integers (while I was thinking of those two constants as unsigned), and
complained that 1 as a bit field was too small, not having enough room
for the sign bit any integer should have. I do remember I was not happy
being forced to use 2 bits for holding a boolean.
While it is true that the bit field could be made smaller, and more
tight for the value it receives, I'm rather surprised to see that this
will be an error in some incoming GNU C compiler. A warning, I would
easily understand. But an error? Does it mean that the programmer is
about to loose, with this incoming compiler, the freedom of deciding the
precise bit allocation of his fields? It looks pretty wrong to me.
What is the rationale?
