Only define loff_t for __USE_MISC (bug 14553).
Bug 14553 reports that sys/types.h defines loff_t unconditionally, despite it not being part of any supported standard. This is permitted by the POSIX *_t reservation, but as a quality-of-implementation issue it's still best not to define it except for __USE_MISC. This patch conditions the definition accordingly, updating a macro in sysdeps/unix/sysv/linux/sys/quota.h to use __loff_t so it still works even if __USE_MISC is not defined. codesearch.debian.net suggests there are quite a lot of loff_t uses outside glibc, but it might well make sense to change all (few) uses of loff_t or __loff_t inside glibc to use off64_t or __off64_t instead, leaving only the definitions, treating this name as obsolescent. Tested for x86_64. [BZ #14553] * posix/sys/types.h (loff_t): Only define for [__USE_MISC]. * sysdeps/unix/sysv/linux/sys/quota.h (dqoff): Use __loff_t instead of loff_t.
