Hi, i'm trying to compile gcc 2.7.0 with solaris 2.3 as host and target.

As i don't have any c compiler on this solaris machine, i'm compiling
gcc on an AIX 3.2.5 as build machine.

I'm intending to follow this procedure to obtain gcc compiled to run
on solaris 2.3:

1. Install the gcc 2.7.0 sources on AIX 3.2.5.

2. On AIX 3.2.5 compile gcc with AIX 3.2.5 as build, host and target platform.
$ configure
$ make LANGUAGES=c
$ make stage1
$ make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O" LANGUAGES=c
$ make stage2
$ make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"
$ make compare 
$ make install CC="stage2/xgcc -Bstage2" CFLAGS="-g -O"

3. On AIX 3.2.5 compile gcc with AIX 3.2.5 as build platform, and Solaris 2.3
as host and target platform.

In order to acomplish this, i have installed on the AIX 3.2.5 machine, the 
Solaris 2.3's include files on /usr/local/sun4-solaris/include. The AIX 3.2.5's
include files are in the usual /usr/include directory.

3.1 $ make distclean
3.2 $ configure --build=rs6000-ibm-aix --host=sun4-solaris
--target=sun4-solaris
3.3 $ make LANGUAGES=c

4. Using the gcc obtained on step 3, On Solaris 2.3 compile gcc with Solaris
2.3 as build, host and target platform.

$ make distclean
$ configure
$ make LANGUAGES=c

After i'd completed the four steps, i'd expect to have a native Solaris 2.3
compiler.

However, the point is that the compilation fails in step 3.2 with the
following error:

$ make LANGUAGES=c
as -o crt1.o ./config/sparc/sol2-c1.asm
Assembler:
/config/sparc/sol2-c1.asm: line 1: Invalid source character 0x21
/config/sparc/sol2-c1.asm: line 1: Error In Syntax 
/config/sparc/sol2-c1.asm: line 3: Invalid source character 0x21
/config/sparc/sol2-c1.asm: line 3: Error In Syntax 
/config/sparc/sol2-c1.asm: line 4: Invalid source character 0x21
/config/sparc/sol2-c1.asm: line 4: Error In Syntax 
/config/sparc/sol2-c1.asm: line 5: Invalid source character 0x21
/config/sparc/sol2-c1.asm: line 5: Error In Syntax 
/config/sparc/sol2-c1.asm: line^Cmake: *** [crt1.o] Error 1

I figured out that i need a cross assembler (like GAS) to succesfully compile
gcc on step 3. 

So i installed the binutils sources on the AIX 3.2.5 machine, and compiled
it with AIX 3.2.5 as the build platform, and Solaris 2.3 as the host
and target platform.

$ configure --build=rs6000-ibm-aix --host=sun4-solaris --target=sun4-solaris
$ make

But while compiling binutils-2.5.2/bfd/sunos.c, i got the following error:

 cc -c -g   -I. -I. -I./../include  sunos.c
"./../include/aout/sun4.h", line 3.0: 1506-236 (W) Macro name PAGE_SIZE has
been
 redefined.
"sunos.c", line 1173.8: 1506-025 (S) Operand must be a modifiable lvalue.
make[1]: *** [sunos.o] Error 1
make[1]: Leaving directory `/aca05/appadmin/GNU/binutils/binutils-2.5.2/bfd'
make: *** [all-bfd] Error 1


My questions are:

1. Is my approach to have a native gcc for solaris 2.3 correct?
2. Do i really need a cross assembler, like GAS, to succesfully compile
gcc for Solaris 2.3 on AIX 3.2.5?
3. How can i fix the problem while compiling bfd/sunos.c?

I really appreciate any comment about my approach to compile gcc for
solaris 2.3 on an AIX 3.2.5 machine.

thanks in advance,
