New Revision: 4010
Modified:
trunk/osprey-gcc-4.2.0/gcc/configure
trunk/osprey-gcc-4.2.0/gcc/configure.ac
Log:
Configure fix to handle GNU Gold linker.
Without this change hidden attribute is configured as not being
supported.
We can safely assume that the GNU Gold linker supports this attribute.
I don't know of any Linux distributions that currently use the GOLD
linker by default, we just discovered this issue when /usr/bin/ld was
replaced by a GOLD linker.
