as a followup to an earlier post (which i can't continue the thread
on since i'm posting this from a browser, sorry), here's the error i'm
getting when i use a gcc-4.3 coldfire toolchain to compile
busybox-1.7.2:

init/lib.a(init.o): In function `toupper':
init.c:(.text.toupper+0x0): multiple definition of `toupper'
applets/built-in.o:(.text.toupper+0x0): first defined here
init/lib.a(init.o): In function `tolower':
init.c:(.text.tolower+0x0): multiple definition of `tolower'
applets/built-in.o:(.text.tolower+0x0): first defined here
... etc etc lots more of these, all related to tolower and toupper ...
ok, let's see what's happening here:
$ nm applets/built-in.o
...
00000000 T tolower
00000000 T toupper
...
ok, so it appears that applets/built-in.o does indeed define those
text symbols. and:
$ nm init/init.o
...
00000000 T tolower
00000000 T toupper
...
but that's using the newer gcc-4.3 toolchain. if i clean and
rebuild using the earlier gcc-4.1 coldfile toolchain, the build works
and:
$ nm applets/built-in.o
... no definition of tolower or toupper ...
$ nm init/init.o
... here either ...
i'm confused ... why should upgrading my toolchain suddenly result
in the definition of text symbols "tolower" and "toupper" in various
object files, causing a link error?
