Instead, I would add a -DEXPORT=... define when compiling the test(they all use the compile_function so can be added there. And then in the string you can just do EXPORT extern.

[apwojcik]

Done

[pfultz2]

I dont think quotes is needed for these flags.

It fails execution on Linux if "" is missing.
