The order of starfile in specs seems to be important.

Good morning.

I try to compile a toolchain for arm7tdmi (gameboy) providing 
binutils-2.15, gcc-3.4.3 and newlib-1.13.0.
I build it under slackware 9.1 with gcc 3.2.3.

I apply a patch to the sources to provide a start code, linkscript and 
syscalls for my target.

The build process go well.

I can use the toolchain and build examples (a simple hello world for 
example) with it.

The problem is that the examples don't run on the target. I found one 
solution and i wonder if it is the good one.

In the file $(PREFIX)/lib/gcc/$(TARGET)/$(GCC_VER)/specs i switch the 
order of the startfiles from :
[code]
*startfile:
  crti%O%s crtbegin%O%s crt0%O%s
[/code]
to :
[code]
*startfile:
  crti%O%s crt0%O%s crtbegin%O%s
[/code] .

Then every thing go well.

My questions are :
   Does the order is important ?
   If no, where could be the real problem ?
   If yes, can i modify it before compiling gcc (within my patch for 
example) ?


Thanks.

Paul.
