.hash sections slightly increasize size of executables/libraries. -Wl,--hash-style=gnu is a completely safe flag (on architectures which support .gnu.hash), so having it in default LDFLAGS wouldn't cause any problems. Having 2 or 3 flags in LDFLAGS isn't too screwing. Using -Wl,--hash-style=gnu would also allow for easier detection of packages which ignore LDFLAGS. -- Arfrever Frehtes Taifersar Arahesis
