standard COFF section. The ELF format for the symbols differs from
the format defined in elf/external.h. It seems that a normal ELF
32-bit format is used, and the representation only changes because
- longs are 64-bit on the alpha. In addition, the handling of
+ longs are 64-bit on the alpha. In addition, the handling of
text/data section indices for symbols is different from the ELF
ABI. As the BFD linker currently does not support dynamic linking
on the alpha, there seems to be no reason to pollute BFD with
