Anyone with a more profound gcc knowledge has an opinion on this?

Hi. I'm running Perl on Linux, and have wondered why the 'Configure' script suggests using '-rdynamic' for linking the Perl binary. The GCC documentation does not mention '-rdynamic', and after hunting around a bit for some info on it I found that it appears in the gcc specs file, and is apparently another way to specify '--export-dynamic'. So, instead of using this undocumented (in my GCC-3.5 CVS code) flag, replace it with a call to the linker to use '--export-dynamic'. I don't have a patch prepared, but all that would be required would be to change line 7630 in Configure from linux) dflt='-rdynamic' ;; to linux) dflt='-Wl,-E' # or '-Wl,--export-dynamic'. When configuring Perl, I've been replacing '-rdynamic' with '-Wl,--export-dynamic', and things have worked flawlessly. Thanks for hearing me out, and thanks to all the Perl developers.
