Bill,
According to...
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43170#c68
the attached changes should be sufficient to eliminate
the configure failures in the tls detection. Can you
try the stock gcc45-4.5.0-1000 packaging with the
attached patch appended to gcc45.patch on a problem
machine?
Jack
ps If that is insufficient to fix the build, try appending
the second patch instead, tls_configure.patch2, which resorts to
making the symbols volatile as well.
