Sorry, I completely misread the PR.  It is not related.

OK, but if I don't apply the patch, GNAT complains that the alignment 
should be 4, not 2 and compiling ceases.

OK, but all systems build it, as it is unconditionally defined in 
Makefile.rtl::GNATRTL_NONTASKING_OBJS

And here it exists in a i686-linux build:

[nick@nick rts]$ ls -l s-aux*
lrwxrwxrwx  1 nick nick    50 Mar 18 12:51 s-auxdec.adb -> 
/home/nick/riscos-elf/gcc-4.0/gcc/ada/s-auxdec.adb
lrwxrwxrwx  1 nick nick    50 Mar 18 12:51 s-auxdec.ads ->
