4379343f92 If multiple compile units are seen then emit them independently. In other words, do not force all DIEs into first, whatever it is, compile unit. 
Note, multiple compile unit support is not well tested (it did not work correctly until now anyway.)

067c48f7a6 Linux wants the FDE initial location and address range to be forced to 32-bit. 
Darwin doesn't. Make this optional for platforms.

4749654506 The FDE initial location and address range data should be free to be 64-bit 
(quad) on a 64-bit platform. This fixes a problem with EH frames on Darwin.

7593f0004f Fix bug 3202. 
The EH_frame and .eh symbols are now private, except for darwin9 and earlier.
The patch also fixes the definition of PrivateGlobalPrefix on pcc linux.
