[Clfs-dev] configure: error: compiler support for visibility attribute is required

[Pierre Lorenzon]

Hi,

After investigating gcc code itself I discovered that the error
message I got appears when HAVE_GAS_HIDDEN is not defined. This
macro is likely to be defined at gcc configure stage. So I'll
investigate why it it is not set to TRUE or 1 of whatever not
ZERO !

Regards

Pierre
