# In compiling up the Expat.so, we want to change from the (likely) situation where
# the default flags MakeMaker provides means that libssp (an internal library to gnu's
# libc) is specified.  The follow lines look for 'stack-protector' and change it to
# 'no-stack-protector' if present. 
# We do this so we don't end up dynmaically relying on libssp.so for Expat.so, because some
# distribution of Linux only provide libssp.a.
