This ticket transfers into Trac an issue originally discussed in the Trac
system at [http://rt.perl.org/rt3/Ticket/Display.html?id=62010 RT #62010].
In that ticket, Donald Hunter said:
''"This patch fixes a problem with gcc 3.4.6 on Linux where
-fvisibility=hidden is detected as supported but
__attribute__((visibility("default"))) is not used for PARROT_EXPORT. The
setting for export visibility was hard-coded for gcc > 4.0 so I changed it
to be a new test based on the detection of support for
-fvisibility=hidden''
''"I created a new file for the config step because it has to happen after
config/auto/warnings.pm and there's no other relevant file to put it
in."''
However, a number of Parrot developers (including myself) were skeptical
of the need for a new configuration step as proposed in that RT.
Discussion was inconclusive.
infinoid, can you take this ticket?
Thank you very much.
