PPC/GAS: Correct a signed vs unsigned comparison error with GCC 4.1
Fix a build error:
cc1: warnings being treated as errors
.../gas/config/tc-ppc.c: In function 'ppc_dwsect':
.../gas/config/tc-ppc.c:4091: warning: comparison between signed and unsigned
make[4]: *** [config/tc-ppc.o] Error 1
observed with GCC 4.1.2 with the `powerpc-beos' target.
Here `flag' identifies the type of a DWARF section, as used with the the
first operand to the `.dwsect' pseudo-op, and has no notion of a sign,
or for that matter being arithmetic in the first place[1]. We already
handle this correctly with the `flag' member of the `xcoff_dwsect_name'
structure, however not in the local variable used in GAS to hold the
parsed value of said `.dwsect' pseudo-op's operand.
Use an unsigned data type in GAS then too, observing that both `offsetT'
and `valueT' have the same width, as they correspond to `bfd_signed_vma'
and `bfd_vma' respectively.

* config/tc-ppc.c (ppc_dwsect): Use `valueT' rather than
`offsetT' as the type of `flag'.
