You could probably do it with quite a bit of work (recompiling gcc). I've
never actually done it, but once I ran across the following in
"m68kpalmos.h", which is part of the gcc source code:
/* -l makes the assembler generate .w branches only */
#undef ASM_SPEC
#define ASM_SPEC "-mno-68881 -m68000 -l "
Dunno if there is a better way to do it. Note that the choice of 16-bit
jumps vs. 32-bit jumps can be an assembler option (like in this case), not
a GCC option, so you need to look there...
