In this case it would be kernel version, since it's a <sys/ucontext.h>
header for the first part.  That problem is with a 2.0.36 kernel, patch
at the end.

The second trip-up was in the java code (building gij), which was looking
for _IO_2_1_stderr_, which in newer relases (glibc-2.1.7) is in libc, but
is not in the problem release glibc-2.0.7.  I didn't chase down a
workaround for that one, I just did a make -t in the java directories :-(

Oh, one other bit I forgot to mention, on Tru64 Unix (alpha-dec-osf4.0d)
I had to build gcc/combine.o with -O instead of -O2, I was getting
"Virtual memory exhausted: Not enough space".  Not sure if it
would have worked with more swap, it's got 128M...

At times like this I'm glad I harranged my management into letting me
put up a one-of-each build cluster :-)

Hope this is useful info,

Marc
