+Add autoconf tests for size_t and ssize_t. Sort-of resolves public issue 79;
+it would solve the problem if MSVC typically used autoconf. However, it gives
+a natural place (config.h) to put the typedef even for MSVC.

+
+When we compare the number of bytes produced with the offset for a
+backreference, make the signedness of the bytes produced clear,
+by sticking it into a size_t. This avoids a signed/unsigned compare
+warning from MSVC (public issue 71), and also is slightly clearer.
+
+Since the line is now so long the explanatory comment about the -1u
+trick has to go somewhere else anyway, I used the opportunity to
+explain it in slightly more detail.
+
+This is a purely stylistic change; the emitted assembler from GCC
+is identical.

+
+In the fast path for decompressing literals, instead of checking
+whether there's 16 bytes free and then checking right afterwards
+(when having subtracted the literal size) that there are now 
+5 bytes free, just check once for 21 bytes. This skips a compare
+and a branch; although it is easily predictable, it is still
+a few cycles on a fast path that we would like to get rid of.
+
+Benchmarking this yields very confusing results. On open-source
+GCC 4.8.1 on Haswell, we get exactly the expected results; the
+benchmarks where we hit the fast path for literals (in particular
+the two HTML benchmarks and the protobuf benchmark) give very nice
+speedups, and the others are not really affected.
+
+However, benchmarks with Google's GCC branch on other hardware
+is much less clear. It seems that we have a weak loss in some cases
+(and the win for the “typical” win cases are not nearly as clear),
+but that it depends on microarchitecture and plain luck in how we run
+the benchmark. Looking at the generated assembler, it seems that
+the removal of the if causes other large-scale changes in how the
+function is laid out, which makes it likely that this is just bad luck.
+
+Thus, we should keep this change, even though its exact current impact is
+unclear; it's a sensible change per se, and dropping it on the basis of
+microoptimization for a given compiler (or even branch of a compiler)
+would seem like a bad strategy in the long run.

+Make the two IncrementalCopy* functions take in an ssize_t instead of a len,
+in order to avoid having to do 32-to-64-bit signed conversions on a hot path
+during decompression. (Also fixes some MSVC warnings, mentioned in public
+issue 75, but more of those remain.) They cannot be size_t because we expect
+them to go negative and test for that.
+
+This saves a few movzwl instructions, yielding ~2% speedup in decompression.

+Windows does not have struct iovec defined anywhere,

+The bulk of this patch was contributed by Mohit Aron.
