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

Subject: Replacing '-rdynamic' in Configure script
----

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.
