If you're building through setuptools, then it's a setuptools bug (they own
distutils going forward). https://github.com/pypa/setuptools
If you're not, please try with setuptools in the picture. It shouldn't require
any more than just importing its "setup()"
New submission from John Ehresman :
Compiling pillow for a debug build fails without -j1 because distutils
parallelizes the build, but there are problems with locking the .pdb file
during when compiling the C files. An example of the error message from a
cl.exe command is:
fatal error
