This is the default on Linux. * sysdeps/unix/sysv/linux/configure.in: Define malloc to new-malloc by default. * new-malloc/Makefile: New file. Improved malloc implementation. * new-malloc/malloc.c: Likewise. * new-malloc/malloc.h: Likewise. * new-malloc/mallocbug.c: Likewise. * new-malloc/obstack.c: Likewise. * new-malloc/obstack.h: Likewise. * new-malloc/thread-m.h: Likewise. * time/Makefile: Compile ap.c with NO_MCHECK flag for now. * time/ap.c: Don't call mcheck if NO_MCHECK is defined. * resolv/Makefile: Add rule to rebuiild libresolv.so when libc.so changed. * stdio/feof.c: Update copyright. * stdio/stdio.h: Add field for lock to FILE structure. Add cast to *MAGIC constants to prevent warnings. * stdio-common/bug7.c: Correct test. Stream must not be closed twice. * stdlib/Makefile (routines): Add secure-getenv. * stdlib/secure-getenv.c: New file. __secure_getenv function moved to here from sysdeps/generic/getenv.c. Otherwise an application cannot replace the getenv function in the libc. * sysdeps/generic/getenv.c: Remove __secure_getenv function. * sysdeps/stub/getenv.c: Remove __secure_getenv alias. * sysdeps/mach/libc-lock.h: Define__libc_mutex_lock to __mutex_lock. * sysdeps/posix/fdopen.c: Update copyright. Don't use EXFUN. * time/test-tz.c: Comment fifth test out. PROBLEM. * time/tzset.c: De-ANSI-declfy. (__tzset): Don't increment pointer tz when no DST information is given.
