Hi,
I'm making some progress with this, but have hit a sticking point and am
looking for a hint. Most of the compilation seems to be going ok, after some
liberal use of f2c, but I'm getting compile errors in src/main/connections.c :
connections.c:926:43: error: use of undeclared identifier 'SSIZE_MAX'
if ((double) size * (double) nitems > SSIZE_MAX)

Recall that I'm compiling with emscripten, which uses clang to generate LLVM
bitcode, which is then converted to javascript. I'm currently using the
existing autotools build scripts, which emscripten tries to twist in to doing
something sensible. It's quite possible that it's ending up mis-"./configure"d
though.
I appreciate this is fairly off-topic, but if anyone has any pointers where to
start looking, they would be greatly appreciated :-)
Thanks,
Jony
