Yet big-scheme.txt says:
  (DELETE <predicate> <list>) => <list>
    [...]
    reuse the storage of the list argument.  DELETE removes all elements
    for which <predicate> is true.

This seems to be a scsh bug -

building scheme48 without setitimer ?

A system I'm trying to build scheme48-0.49 on (Unicos on Cray J90) doesn't have
the function setitimer.

However, even though c/sysdep.h produced by configure 
says #undef HAVE_SETITIMER,
this seems to have no effect on the compilation.
(as a matter of fact, I don't see HAVE_SETITIMER tested anywhere
in the source...)

How can this be fixed?

Thanks in advance,
Dmitrii.

PS. I get the following:

 Unsatisfied external references
 Entry name      Modules referencing entry 

 setitimer       event$c

 ldr-112 cc: WARNING 
     Because of previous errors, file 'scheme48vm' is not executable.
make: *** [scheme48vm] Error 1

PPS. In fact, the story is more complicated: the linker
produces just a warning when it gets an unsatisfied external reference.
Thus configure is not working properly when it comes to detect

The simplest thing to do would be to write your own setiitimer
procedure.  All setitimer does is schedule a periodic interrupt.  It's
basically a better version of the old alarm system call that allows
you to choose between counting in real time and counting used CPU
time, to set a timer to go off at regular intervals, and use
scheduling intervals of less than a second.
