JNAerator fails on GnuTLS header for JNA runtime #61

I tried to run JNAerator on gnutls.h. After playing around with different command-line options, I've been unable to get the correct output.

I'm using the pre-built Win32 binary package from ftp://ftp.gnutls.org/gcrypt/gnutls/w32/. I have placed JNAerator in the include directory so it will find the related headers.

If I run this:

java -jar jnaerator-0.12-20140222.210027-44-shaded.jar -mode Directory -runtime JNA -f -beautifyNames -library gnutls -v gnutls/gnutls.h

JNAerator "succeeds" in that it outputs GnutlsLibrary.java, but this generated file only contains definitions of constants. It does not contain ANY functions defined in gnutls.h.

If I add the -parseChunks option, JNAerator fails with a NullPointerException:

Regular parsing took too long, now trying to parse sources slice by slice.

Just tried this with version 0.11. Behavior without -parseChunks is the same as latest snapshot, but it appears to work correctly with -parseChunks.
