[Bug c/15790] New: Alignment error building gcc with i686-coff target

[richard dot parratt at netiq dot com]

I was trying to build a GCC cross compiler with a target of "i686-coff". 
It failed with "Error: Alignment not a power of 2"

I found various references to this, e.g. 
http://sources.redhat.com/ml/crossgcc/2001-03/msg00176.html
 from Kai Ruottu <kai.ruottu@luukku.com>

The fix given there was to add lines as follows to i386-coff.h: #undef 
ASM_OUTPUT_ALIGN
#define ASM_OUTPUT_ALIGN(FILE,LOG)    \
    if ((LOG)!=0) fprintf ((FILE), "\t.align %d\n", 1<<(LOG))

This worked.

As this seems to be an old chestnut (it was already one in 2001) could the fix 
be added to the reference source, so that everyone making a cross-compiler 
doesn't have to patch?
