I recently rewrote 'gcjh' in java, including all the bits needed for 'javah'-like operation. I'd like to check it in. However, when I wrote it I used the ASM library. My preferred approach to this would be to check in the needed ASM sources (in tools/external), and build the library as part of the Classpath build. That way we wouldn't have any java-based external dependencies. On irc Mark suggested a --with-asm configure option. I could do that, instead, though it would make the eclipse-based build a bit weird. Any other ideas? I'm happy to send the code to anybody who wants it. It depends on the classpath getopt code. Tom
