While attempting to compile gcj on my mster branch ( https://github.com/Zopolis4/gcj/tree/mster) , the compilation fails because several files within libjava are unable to include ffi.h because they cannot find it.

We only ever built libjava as part of a whole-GCC build. The libjava directory isn't intended to be built on its own. Please build the whole GCC tree using the top-level makefile and it'll work, then you can extract whatever built pieces you need. -- Andrew Haley (he/him) Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> https://keybase.io/andrewhaley EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
