Comment:
I've now developed a TEMPORARY fix for this, which needs a review.
Change GuessSmallNB() in src/tune/blas/gemm/mmsearch.c
as suggested by Clint Whaley to return 28
on Solaris. This is ONLY A TEMPORARY FIX and once the real problem
in the function is sorted out, this fix will need to be removed. But
for now it permits ATLAS to build on a Sun T5240 with gcc-4.4.0.
Apart from the comments, the only change to the C source code is to add
{{{
return(28);
}}}
at the top of the function GuessSmallNB(). This fix is only implemented on
Solaris, as the spkg-install now includes:
{{{
import shutil
if os.uname()[0] == 'SunOS':
shutil.copy2('patches/mmsearch-with-temp-Solaris-
fix.c','src/tune/blas/gemm/mmsearch.c')
}}}
With this patch applied, ATLAS builds on Solaris, with the next Solaris
failure being in 'linbox'.
Once an ATLAS developer is able to find the real reason for the failure,
an update of the ATLAS source could should be implemented, which will mean
we will mean this patch should be removed at a later date.

I've NOT used 'hg' to commit this in any way (not even sure if I'm
supposed to do that or the reviewer), so can the reviewer please do this
for me.
