What fields or structures are you trying to get at?  I haven't needed
to include siginfo.h explicitly even though this file pokes and prods
pretty thoroughly at the siginfo structures:

http://git.kernel.org/?p=fs/ext2/e2fsprogs.git;a=blob;f=e2fsck/sigcatcher.c;h=10b93287d5b2b4da1fb43d34fafd848d06c01645;hb=5f7c04972fefa8198c34f231a9e8a5430705b4ab

The sigcatcher.c file is a debugging tool for e2fsprogs that prints
pretty much everything that is available to userspace, as far as I
know...
