* FIXME: The setjmp/longjmp approach works in Red Hat 4.2 but
* not in Red Hat 5.1 for Linux/Sparc. We should talk to the
* maintainer of Linux/Sparc glibc2 about this. Or we can write
* assembly code to save and restore thread contexts. Before
* this problem is solved, you can build the pthreads version.
* Set the environment variable USE_PTHREADS to 1 before you
* build.
* You need glibc2-2.0.7-25 or later. The libraries that came with
* Red Hat 5.1 are not new enough, but they are in 5.2.
