xmgrace problem

[rudra-b]

while trying to compile grace (5.1.22), I am facing problem:

$ make
make[1]: Entering directory `/home/rudra/Downloads/grace-5.1.22/cephes'
gcc -O2 -m486 -fno-common -Wall -Wpointer-arith -Wnested-externs -I.. -I.    -c -o airy.o airy.c
cc1: error: unrecognized command line option "-m486"
make[1]: *** [airy.o] Error 1
make[1]: Leaving directory `/home/rudra/Downloads/grace-5.1.22/cephes'
make: *** [subdirs] Error 1

if I remove m486 option in Make.conf, I am getting another error:

In file included from /usr/include/stdio.h:34:0,
                 from mtherr.c:60:
/usr/lib/gcc/i686-redhat-linux/4.5.1/include/stddef.h:211:23: error: duplicate ‘unsigned’

make[1]: *** [mtherr.o] Error 1
make[1]: Leaving directory `/home/rudra/Downloads/grace-5.1.22/cephes'

Attached is my config.log
my system is

$ uname -r
2.6.35.9-64.fc14.i686

and my gcc is:

$ gcc -v

I am forced to use source because rpm is also giving some problem and crashing while starting.

Doesn't rpmfusion have a grace package?

BTW, this smells like a macro problem. Rerun gcc adding -fsave-temps. Examine the .i (or .ii) file to see what the offending line looks like after running through cpp.
