# Workaround for http://gcc.gnu.org/PR55489.  Happens with -fPIE/-fPIC and

# large functions that use global variables.  The bug is in all releases of

# GCC, but it became particularly acute in 4.6.x and 4.7.x.  It is fixed in

# 4.7.3 and 4.8.0.  We should be able to delete this at the end of 2013.
