Here (closely related Fedora 18), /usr/lib/libgcc_s.so.1
is part of package libgcc
, which is described as "This package contains GCC shared support library which is needed
e.g. for exception handling support.". It should be safe to install (and probably is installed already, if any C++ code is deployed).
