I'm trying to compile Gnu's regexp-1.0.8.jar to an object file. According to the description on the web, jar Files seems to be allowed as gcj source.
But all I get is the following output:
./gnu-regexp-1.0.8.jar:0: Not a valid Java .class file.
Is there anything I can do?

 gcj 2.95.2 couldn't read compressed zip files.  I bet the .class files
 in your jar are compressed.  Can you find out?
 
 One workaround is to unjar the archive and then compile each .class
 file separately.  Or, you could get the source and compile directly
 from .java.
 
 I haven't tested compiling an entire .jar file so I don't know whether
 or not it actually works.

 You need to get a newwer gcj. 2.95.2 is too old.
 
 However, I'm getting a segfault trying to compile a .jar file with a recent compiler:
 
 (gdb) r gnu-regexp-1.0.8.jar -fno-use-divide-subroutine -fuse-boehm-gc -fasynchronous-exceptions -quiet -dumpbase gnu-regexp-1.0.8.jar -g1 -version -o
 /tmp/cc8fdFdw.s

 So I'm going to modify this PR and keep it open.

    I did the original zlib hacking in gcj, so I'll take a look at the bug Bryce found.
