[Bug 397] New: -fvisibility-inlines-hidden causes undefined symb

A new bug was added:
Summary: -fvisibility-inlines-hidden causes undefined symbols
Product: RTT
Version: 1.0.3
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Build System
AssignedTo: orocos-dev [..] ...
ReportedBy: peter [dot] soetens [..] ...

The RTT 1.0.x releases are compiled with the gcc 4.x flag
"-fvisibility-inlines-hidden". In recent GCC versions, this causes
undefined symbols if different files of the program or library are compiled
with different optimisation flags. I'm not sure if this is a GCC bug or
a 'feature'. Removing this flag causes a larger symbol lookup table, resulting
in a larger library.

This flag was already removed from the RTT 1.2 branch.
