I recently tried to build a gcc cross-compiler, which is revised from gcc-2.6.3.
The building process failed as:

_fixunsxfsi
_fixtfdi
_fixunstfdi
_floatditf
__gcc_bcmp
_varargs
_eprintf
In file included from /usr/include/libio.h:32,

from ./libgcc2.c:1384:

/usr/include/_G_config.h:56: unknown machine mode `_G_uint32_t'
make: *** [libgcc2.a] Error 1

I have searched the internet as more as possible, and found only bigwab came to the most similar problem.
Could anyone solved it now?
Any help is greatly appreciated.

Thanks for your help.
I have also got help from the links:

and

The problems on list are all solved with the suggestions. But still, I came accross the above problem: unknown machine mode

a question
" gcc-2.6.3 "
is there a reason that you must use a 9 year old "out of date" version of the compiler
gcc-2.6.3 and the current is gcc-4.5.2

That's because this cross-compiler was developed by another team, which choose this version of compiler. This cross-compiler is used for simplescalar.
http://www.simplescalar.com/

man that is old - the current was released in 2003
improves the support for the very old and dead rh9

dose this even work on a modern 2.6 kernel seeing as it is designed for the 2.4

form the doc page one of the dependencies is "glibc-1.09" and the current is glibc-2.11.2
http://www.simplescalar.com/docs/install_guide_v2.txt
what operating system are you trying to build this on ?

My host platform is： Fedora Core 13 + x86_64 + gcc4.4.5.

i do not think there is even a 0.00001% ?? maybe chance of this even building ,even after 80+ hours of hacking the source and OS
and a 0.0000% chance of this running on fedora 13
and a 0.0000% of it building with gcc 4.5

i would NEVER even try with this program

if it is a 100% MUST USE ( your bosses boss is forcing the issue ) try a 7 year old and out of date version of red hat ( rh9) in a vm ???
that ???? maybe might ? work

or install rh9 on a OLD computer from 2001 ( it will NOT install on new hardware )

but rh9 has some VERY big security holes in it , ones that a "script kiddy" can sail an aircraft carrier through. - VERY INSECURE
