Omitting the FUSE single thread option (-s), activates mulithreading.

But on Windows all adequate test classes fail to start with:

org.cryptomator.jfuse.api.FuseMountFailedException: Exception when starting fuse_loop. Message: unresolved symbol: fuse3_loop_mt

	at [email protected]/org.cryptomator.jfuse.examples.WindowsMirrorFileSystem.main(WindowsMirrorFileSystem.java:34)

Info: Using fsp_fuse3_loop_mt_31 does the trick. I guess, because the symbol is defined after the normal loop function, it overwrites some internal definition.

@infeo can you ask on the panama-dev mailing list whether this is a problem with the linker?
