run_command_get_outputs() doesn't work on cygwin

[letmaik]

I tried astrometry on Ubuntu and it works great. Now I also wanted to try it on Windows with cygwin. The compile within cygwin went through without problems, but once I run it I get the following error:

$ solve-field.exe test.jpg
Reading input file 1 of 1: "test.jpg"...
jpegtopnm: WRITING PPM FILE
augment-xylist.c:586:backtick Failed to run command: /usr/local/astrometry/bin/image2pnm.py --sanitized-fits-outfile /tmp/tmp.sanitized.ec6ASY --fix-sdss --infile test.jpg --uncompressed-outfile /tmp/tmp.uncompressed.WMDQuS --outfile /tmp/tmp.ppm.b2btvN --ppm
 ioutils.c:627:run_command_get_outputs error reading from child output stream
 system: No such file or directory

When I copy the failed command and execute it manually, it works though:

$ /usr/local/astrometry/bin/image2pnm.py --sanitized-fits-outfile /tmp/tmp.sanitized.ec6ASY --fix-sdss --infile test.jpg --uncompressed-outfile /tmp/tmp.uncompressed.WMDQuS --outfile /tmp/tmp.ppm.b2btvN --ppm

Even if you don't care about Windows :p I wanted to post this here in case anyone with more experience than me who is also trying the same thing can fix it.
