First question:
I utilitied the default configuration for busybox1.4.0,and errors showed:

  SPLIT   include/autoconf.h -> include/config/*
  GEN     include/bbconfigopts.h
  CC      miscutils/bbconfig.o

Another question: if the high version busybox(saying 1.3.2) didn't support
static linking? the errors like:
  CC      applets/applets.o
applets/applets.c:22:2: #warning Static linking against glibc produces
buggy executables
applets/applets.c:23:2: #warning (glibc does not cope well with ld
--gc-sections).
applets/applets.c:24:2: #warning See
sources.redhat.com/bugzilla/show_bug.cgi?id=3400
applets/applets.c:25:2: #warning Note that glibc is utterly unsuitable for
static linking anyway.
make[1]: *** [applets/applets.o] error1
make: *** [applets] error2

Thanks!
