When libunwind is installed on the system, the gcc configure
will enable it automatically by default. As the result, the new
libgcc_s.so.1 is very different and not backward compatible with
the previous libgcc_s.so.1. The new libgcc_s.so.1 depends on
libunwind.so. Many symbols used to defined in libgcc_s.so.1 are
now provided by libunwind.so and unversioned. Anything referencing
those symbols won't work now like:

/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetRegionStart@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_SetGR@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetLanguageSpecificData@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetIP@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetGR@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_SetIP@GCC_3.0' collect2: ld returned 1 exit status
gnatlink: cannot call /usr/bin/gcc
