build error

[d.henman]

I would like advice on how to interpret the following emacs build time error:

Subject cvs date:  Version September 14, 9:25 JST

--- start of paste

In end of data:
bytecomp.el:4255:1:Warning: the function `compilation-forget-errors' is not
    known to be defined.
Wrote /usr/cvs/emacs/lisp/emacs-lisp/bytecomp.elc
Compiling /usr/cvs/emacs/lisp/subr.el
Fatal error (6)/bin/sh: line 4:  3088 Aborted                 (core dumped) 
EMACSLOADPATH=/usr/cvs/emacs/lisp ../src/bootstrap-emacs.exe -batch 
--no-site-file --multibyte -f batch-byte-compile-if-not-done $el
make[2]: *** [compile] Error 1

--- end of paste

I get from this, that subr.el is the file being compliled when core is dumped, 
and
that this is a compiler fatal error #6 ?  or line #4 in some file (can't be the 
.el file)and 3088 being I don't now a line# or error #.

There is a "bootstrap-emacs.exe.stackdump"  being created in the lisp directory.


Thanks for any advice.
