Whoops, answering too quickly...

that library can only build *correctly* under the latest MSVC 14 (aka
Studio 2015)
when you are compiling for 64-bits on Windows (not an issue with 32 bit

In the past, size_t/ssize_t/ptrdiff_t and other alignment primitives failed
correspond to the width of their defined domain (size reflects memory, ergo
thes must be the same size, bitwise, as a void*).  This showed up very
egregiously in nghttp2 which (fairly) demands that the POSIX types reflect
their definitions.

MS finally is catching up to POSIX with their Studio 2015 product release.
So the antique .dsp is something of a red herring, you probably don't want
to ever run an nghttp2 app or library compiled against VC98, if building to
64-bits.  It is hardly a fully-conformant C99 compiler, but it comes a whole
lot closer than previous attempts.
