The sysv gabi says:
"When the link editor combines several relocatable object files, it does not
allow multiple definitions of STB_GLOBAL symbols with the same name. On the
other hand, if a defined global symbol exists, the appearance of a weak symbol
with the same name will not cause an error. The link editor honors the global
definition and ignores the weak ones. Similarly, if a common symbol exists (that
is, a symbol whose st_shndx field holds SHN_COMMON), the appearance of a weak
symbol with the same name will not cause an error. The link editor honors the
common definition and ignores the weak ones."
I interpret "ignores" to mean that whether the weak symbol is present or not,
the end result should be the same. So I think HJ's 9670 patch to merge
visibilty from the weak symbol to the strong one is totally bogus.
