Hi all,

The attached patch implements a new option --eval-command (-ex for
short) which works similarly to the --command option except that it
passes the command itself, rather than a file name containing commands.

In most cases, this eliminates the need for temporary files or messing 
around with stdin when running programs via the debugger.

For example:

gdb hello.exe --batch -ex 'target sim' -ex load -ex run

This option may be used in conjunction with the existing --command (-x)
command and the order of the options is honoured.

It is still necessary to use a script file if define/if/while, or any
other nested construct, is required. Suggestions on how to deal with
this would be welcome.

Note that the patch assumes that the batch-silent and
return-child-result patches have already been applied (although the
implementation in no way depends on those features).

Thanks

Andrew Stubbs
