Not sure, I really get this, sorry.

No, appending to options
would mean that this addition would be parsed by the loop
'foreach opt $options {'
of line 1713,
while adding it to new_options like it
is done also below for 'shlib_load'.
Furthermore, I always feel uncomfortable
when code inside a loop changes the variable
on which the loop is performed (options in that case.)
Wouldn't it be better to also
append to new_options for the two conditions above?
So, what about this?

* lib/gdb.exp (gdb_compile): Append added options
directly to new_options variable.
Add --enable-auto-import option for
mingw and cygwin targets.
