    Thanks for the responses - I will try again with
'--enable-checking=release'.
    But, I still don't think this bug is a "non-issue" - here's why:

    Sorry, but gcc shouldn't be enforcing this on us - I thought it was
    supposed to be capable of being an embedded systems compiler - are
    you saying gcc cannot be compiled or run on any embedded system with
    less than 2GB RAM ?  Surely not!

    Thanks for your response Steven!

    Fair enough, OK, I will.  

    But I'd still like some kind of answer - why MUST insn-emit.c be so large ?
    The answer "compiling lots of small .c files is slower that one large one"
    is demonstrably false on my machine and on many other machines with not
much
    RAM I suspect, and must be qualified with "if you have a platform with X
RAM
    and X CPU speed" . 
    If the gcc build scripts detect they are running on a platform with less
than
    4GB of RAM, say, they could decide to split insn-emit.c .
    Why is it so inconceivable that they might in future do something like this
?
