Ian, Since the proposed patch on darwin (using 'nm -g') reports to configure that -rdynamic is unnecessary on darwin and the resulting gcc build generates code via dragon-egg, I believe we can infer that this isn't an issue on darwin. So I guess my current patch should be best... http://gcc.gnu.org/ml/gcc-patches/2010-04/msg01345.html Of course, it should be adjusted later for Solaris and Irix once they sort out which set of devtools and utilities will be the baseline requirement of compiling plugin support (since the system compilers may not provide -rdynamic and objdump may not be present).
