Bug in egcs-1.1b and snapshot 1998-10-19 (target m68k)

[Peter Jakubek]

Wrong code is generated for 68000 targets when using the d16(Ax) mode.
The range is not correctly checked for 68000/5200 targets.
(offset must be in range [-32768, 32767])

It seems the macro INDIRECTABLE_1_ADDRESS_P(X) causes the trouble:
