Re: TARGET undefined in bucomm.c

[Luke <hazelnusse@gmail.com>]

After unpacking the source tarball, there is only config.in, and it has this:

#undef TARGET
#undef TARGET_PREPENDS_UNDERSCORE

after running configure as I described, it has the same thing, and
config.h has not been generated at this point.

After running make, and failing, config.h is generated and has this:

#define TARGET "arm-none-eabi"
#define TARGET_PREPENDS_UNDERSCORE 0

bucomm.c does not have a line:
#include "config.h"

When I add that line to bucomm.c, bucomm.o is built, but then it fails
again on cxxfilt.c, which also does not #include "config.h".  Here is
the error I get for that:
gcc -DHAVE_CONFIG_H -I.  -I. -I. -I../bfd -I./../bfd -I./../include
-DLOCALEDIR="\"/usr/local/share/locale\""
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT cxxfilt.o
-MD -MP -MF .deps/cxxfilt.Tpo -c -o cxxfilt.o cxxfilt.c
cxxfilt.c:34:31: error: ‘TARGET_PREPENDS_UNDERSCORE’ undeclared here
(not in a function)
make[4]: *** [cxxfilt.o] Error 1

TARGET_PREPENDS_UNDERSCORE is #defined in config.h.  Adding it to
cxxfilt.c lets it compile, but with a warning:
gcc -DHAVE_CONFIG_H -I.  -I. -I. -I../bfd -I./../bfd -I./../include
-DLOCALEDIR="\"/usr/local/share/locale\""
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT cxxfilt.o
-MD -MP -MF .deps/cxxfilt.Tpo -c -o cxxfilt.o cxxfilt.c
In file included from cxxfilt.c:32:0:
config.h:157:0: warning: "PACKAGE" redefined
../bfd/config.h:245:0: note: this is the location of the previous definition

and finally binutils finishes compiling, but then gas fails, with
similar errors that would seemingly be fixed if the appropriate files
were pound including config.h

Is there some other way I should be compiling so that these define
statements are inserted correctly, or should these .c files actually
be #including config.h?  Or maybe the config.h needs to be included in
just one top level header file and that would fix all of this?
