# a mozcomps build, particularly non-optimized builds. To avoid the problem,
# we move the data segment before the code segment in the libraray. The data
# segment is relatively small, and all of the relocations in question
# (which are pointers to construction vtables) reside in the
# (__DATA,__const) section.
