[Buildroot] "multiple target patterns" error while building under cygwin

[Crane, Matthew]

Hi, 
 
Thanks for your response.  I think my build error is the result of the
dos2unix + unix2dos patch.  My cygwin system was installed with Unix
text mode, and I've tried to explicitly set the locale, but fixdep
always seems to output the Dos text. 

I instead used the dos2unix/unix2dos patch to fix the fixdep output,
which I think ending up causing the error below.  Not sure how though,
or how to fix it.  Thanks,

Matt

 
.applets.o.cmd looks like this:
 
cmd_applets/applets.o := <snip>
 
deps_applets/applets.o := \
  applets/applets.c \
    $(wildcard include/config/static.h) \
    $(wildcard include/config/show/usage.h) \
<snip>
 
line 410: applets/applets.o: $(deps_applets/applets.o)
 
$(deps_applets/applets.o):
<eof>
 
I had already patched the make process so that it runs fixdep through
unix2dos, dos2unix similar to this patch I found online:
 
define rule_cc_o_c
     $(call echo-cmd,checksrc) $(cmd_checksrc)              \
     $(call echo-cmd,cc_o_c) $(cmd_cc_o_c);                  \
+    dos2unix $(depfile);                                              \
     $(cmd_modversions)                          \
-    scripts/basic/fixdep $(depfile) $@ '$(call make-cmd,cc_o_c)' >    \

+ scripts/basic/fixdep $(depfile) $@ '$(call make-cmd,cc_o_c)' |
unix2dos > \ 
                                                   $(dot-target).tmp;  \
     rm -f $(depfile);                          \
     mv -f $(dot-target).tmp $(dot-target).cmd

It proceeded to build, but failed with the above error.   Maybe related,
not sure.  I'm looking forward to the day when cygwin support is
completely transparent in buildroot, soon I'm sure.

Please paste lines 409-411 (take care not to word-wrap it).
Just to be sure, untar the busybox into a separate dir, then 'make
defconfig && make'. I expect this to happen there too..

thanks,
