Hi Jeremy,

I have installed the latest cygwin version and was able to process all
flex/bison files. The cygwin flex version can handle "/" as path
separator, too :-) Apart from that I had the same problems compiling
"oslinfo", "oslquery", "oslcomp" and "exec" projects. I have found c99
macro definitions

and

Maybe we can use CUDA or OpenCL (which is better, since available on
NVIDIA/ATI) for all missing math functions. Please see

- http://developer.download.nvidia.com/compute/cuda/2_3/toolkit/docs/NVIDIA_CUDA_Programming_Guide_2.3.pdf,
page 120
- http://www.khronos.org/registry/cl/specs/opencl-1.0.43.pdf?q=specification,
page 168

Regards,
Oleg

My generated code issues were from VS having not rebuilt the files with the
new flex.

So now I am just left with a bunch of missing math functions.
It looks likes visual studios implementation of math. or cmath is missing a
lot of the functions.

Things like
log2f, logbf, truncf, etc
and defines like M_E, M_1_PI, M_PI_2 etc.

See if you run into the same thing and then im not sure where to go from
here.

I guess we should get some feedback from others, maybe they are available
somewhere else, or I could be missing something.
