It turns out that DODMALLOC was broken when I reorganized busybox.h header file usage before the 0.49 release. To fix it, I had to move the '#include "busybox.h"' to the end of the list of #include files. -Erik 2001-02-20 06:14:08 +00:00			`#include "busybox.h"`

Robert P. Day removed 8 gazillion occurrences of "extern" on function definitions. (That should only be on prototypes.) 2006-03-06 20:47:33 +00:00			`int length_main(int argc, char **argv)`
Don't use strings directly in calls to usage(). This is in preparation for their extraction to a separate file. 2000-07-14 23:28:47 +00:00			`{`

...and yet another small fix. Ouch... 2006-10-26 23:39:04 +00:00			`printf("%lu\n", (unsigned long)strlen(*argv));`
