Hi,
when building GCC with clang, it warns that the private member suffix
in class ltrans_file_cache (defined in lto-ltrans-cache.h) is not used
which indeed looks like it is the case. This patch therefore removes
it along with its initialization in the constructor.
Bootstrapped and tested on x86_64-linx. OK for master?
Alternatively, as with all of these clang warning issues, I'm
perfectly happy to add an entry to contrib/filter-clang-warnings.py to
ignore the warning instead.
Thanks,
Martin

not initialize member prefix.
