Subject: Disallow gcc versions 4.1.{0,1}
X-Git-Tag: v2.6.29-rc1~547
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f9d14250071eda9972e4c9cea745a11185952114;p=pandora-kernel.git

Disallow gcc versions 4.1.{0,1}

These compiler versions are known to miscompile __weak functions and
thus generate kernels that don't necessarily work correctly.  If a weak
function is int he same compilation unit as a caller, gcc may end up
inlining it, and thus binding the weak function too early.

See

    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27781

for details.
