RE: [PATCH] Re: Problem on rs6000-ibm-aix4.3.2.0 (Fortran) -DPIC

Guido,

Can you show me an example of a situation where there is
pic and non-pic code created by a compiler that doesn't define
some preprocessor macro for PIC?
Then if you find one, does it support inline assembler?
I have a hard time believing there is anyone out there using
Libtool who is going to be burned if they change "PIC" to
"__PIC__ || __pic__" in their code, and we drop it entirely.
Maybe I'll volunteer to fix every instance that it would.  ;)

I've abused it a number of times for "#ifdef SHARED", i.e. to
distinguish the current $COMPILE as being for .o/.a or some
.lo/.la/.so - how to mimic such without -DPIC?
