[RFA] patch for mips gdb build failure with latest gcc

[Fred Fish <fnf@fishpond.ninemoons.com>]

Gdb for mips does not currently build with the latest gcc.  The error
message is:

  In file included from support.c:26:
  sim-main.h:370: unnamed fields of type other than struct or union are not allowed

The problem is an enum declaration inside a struct declaration, which
is apparently now illegal.  This patch fixes it.


  2001-11-17  Fred Fish  <fnf@redhat.com>

	* sim-main.h (float_operation): Move enum declaration outside
	of _sim_cpu struct declaration.
