Re: [PATCH/RFA] sim autoconf conversion fallout

There still a lot of breakage in the sim tree:

This problem applied to just two simulators: MIPS and mn10300. I've fixed the error and confirmed that the MIPS builds.

* The --enable-sim option is essentially a no-op now, since all
  simulators are built unconditionally if gdb is configured for a
  matching target.  Why has the option been retained while all the
  logic that used it is gone?  Why was the logic removed in the first

--enable-sim always was a no-op (unlike --disable-sim). The only exception was for erc32 and since that doesn't build at all I've now disabled it.

* In the past several simulators were only built when compiling with
  gcc.  That code was ripped out.  Why?

Why not.

From '98 (although I suspect '96):
  # The PowerPC simulator uses the GCC extension long long as well as
  # ANSI prototypes, so don't enable it for random host compilers
  # unless asked to.
hence the test.

Fast forward 7 years - even GCC now assums ISO-C and long-long is a defacto "standard".
