Well, a trivial point for patching purposes is that /usr/include/sys/errno.h
is nothing more than "#include <errno.h>".
Whatever. Do the right thing.
So, in /usr/src/linux-1.1.54/include/linux/errno.h, the actual value for
EWOULDBLOCK is EAGAIN. S48 chokes on this as an undefined symbol.
Elsewhere in errno.h, "#define EAGAIN 11;". I replaced 'EAGAIN' with 11
which resolved the immediate problem and revealed another one, the clue for
which is in the appended make.err file.
You have to put in a numeric value, as I said in my earlier msg.
You have the exact same problem with i386_linux/signal.scm.
Obviously, whoever made these linux files just made them from
the original .h files using some emacs macros, and didn't check
the results very carefully.
If you have any other problems, they should be of a similarly trivial
nature. All these numeric definitions in i386_linux have to be *numeric*.
