- Subject: [patch/m68k] convert USE_GAS into a compile-time constant
Hello!
This patch converts all uses of USE_GAS into a compile-time boolean. That
way it can be used in C expressions just like MOTOROLA. Tested by compiling
cc1 with m68k-elf as target.

* config/m68k/m68k.h: Make USE_GAS a compile-time boolean.
* config/m68k/m68k.c (m68k_output_pic_call, m68k_output_mi_thunk):
Replace "#ifdef USE_GAS" with C statements.
* config/m68k/m68k.md (anonymous call and call_value define_insn):
Likewise.
