vcs-svn: suppress -Wtype-limits warning
On 32-bit architectures with 64-bit file offsets, gcc 4.3 and earlier
produce the following warning:
CC vcs-svn/sliding_window.o
vcs-svn/sliding_window.c: In function `check_overflow':
vcs-svn/sliding_window.c:36: warning: comparison is always false \
due to limited range of data type
The warning appears even when gcc is run without any warning flags
(PR12963). In later versions it can be reproduced with -Wtype-limits,
which is implied by -Wextra.
On 64-bit architectures it really is possible for a size_t not to be
representable as an off_t so the check being warned about is not
actually redundant. But even false positives are distracting. Avoid
the warning by making the "len" argument to check_overflow a
uintmax_t; no functional change intended.
