This gets added by libtool.m4 here (line 4311):
case "$host_os" in
# For platforms which do not support PIC, -DPIC is meaningless:
*djgpp*)
_LT_AC_TAGVAR(lt_prog_compiler_pic, $1)=
;;
*)
_LT_AC_TAGVAR(lt_prog_compiler_pic, $1)="$_LT_AC_TAGVAR(lt_prog_compiler_pic, $1)
-DPIC"
;;
esac
This seems quite wrong. Why do we assume the compiler will grok -DPIC?
Why isn't this handled in the tag-specific and os-specific portions of
libtool.m4? If the tag/os combo says -KPIC is needed, why do we -KPIC
-DPIC?
