Duplicated enums building gcc-4.7.0 on AIX6.1

Duplicated enums building gcc-4.7.0 on AIX6.1

[John M Collins]

Please could you send any replies to my email address too as I'm not
subscribed - thanks.

I'm trying to build gcc-4.7.0 on AIX6.1 where there is a version of
gcc-4.6.3 on without all the bits I want such as C++ (and built with a
funny --prefix).

From an empty directory I am doing:

../gcc-4.7.0/configure --prefix=/usr --enable-langauges=c,c++
make bootstrap

(I've tried the configure with --disable-multilibs in case that makes
any difference but it doesn't).

It goes for a while and then I get to:

gcc -c   -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings
-Wcast-qual -Wstrict-prototypes -Wmissing-prototypes
-Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros

I've looked at gcc/options.h and indeed there are duplicated enums in there.

Is there any way I can move this one on?

Thanks for any help you can give.
