+# rediffed against whatever busybox ptxdist-0.3.23 uses.

+# libbb/syscalls.c:43: error: asm-specifier for variable `__sc_4' conflicts with asm clobber list
+# libbb/syscalls.c:43: error: asm-specifier for variable `__sc_5' conflicts with asm clobber list

+# See also http://lists.debian.org/debian-glibc/2003/debian-glibc-200305/msg00190.html
+# A similar fix is needed for fdisk.c
