Would be really neat to have pre-compiled ISPCTextureCompressor binaries in cases like this...

Adding

#include <limits>

to ispc_texcomp/ispc_texcomp_astc.cpp solves it.

Compiled libispc_texcomp.so for Ubuntu 16.04: https://github.com/procedural/img2ktx_binaries_ubuntu_16_04/blob/master/third_party/ISPCTextureCompressor/build/libispc_texcomp.so
