Building GCC 4.3.2 on powerpc-yellowdog-linux-gnu

[Angel Tsankov]

Hi,

I'm trying to build (natively) GCC 4.3.2 on a
powerpc-yellowdog-linux-gnu. I have not yet managed to build it all
('make bootstrap') but I found out that each of the following changes
(applied in the order specified) takes me further on:

-- clear the LIBRARY_PATH variable, i.e. build with 'env LIBRARY_PATH=
    make bootstrap';
-- insert '#include <limits.h>' in libcpp/include/line-map.h:26 (to work
    around errors about undefined CHAR_BIT or UINT_MAX);
-- insert '#include <limits.h>' in gcc/real.h:29;
-- add BOOT_CFLAGS='-DENABLE_DECIMAL_FLOAT=1
    -DENABLE_DECIMAL_BID_FORMAT=0' to 'make bootstrap' since these
    macros were not defined (this is stage 2);
-- insert '#include <limits.h>' in gcc/hard-reg-set.h:24;
-- insert '#include <limits.h>' in gcc/toplev.h:24;
-- added -DHAVE_LIMITS_H to BOOT_CFLAGS;
-- added -DHAVE_GAS_SHF_MERGE=0 to BOOT_CFLAGS;

I wonder if these steps will eventually take me to a successful build of
GCC. In case this matters, the configuration script identifies the
build, host, and target systems as powerpc-unknown-linux-gnu.

Thanks in advance,
