Err...  Why was this ok for UnixWare (sco5) and Solaris2/x86 without
gas, but it isn't for FreeBSD 2, even though it works?  Or, phrasing
the question another way, why would it be better to always use
DW_EH_PE_absptr instead of PE_indirect and PE_datarel when possible?
If the default version is indeed better, should I go ahead and change
the similar patches installed in gcc/config/i386/sol2.h and sco5.h?
