[llvm-commits] [Review request] Tweak section names of linkonce on PECOFF

[NAKAMURA Takumi]

Good morning, Anton.

I am sorry, it was my mistake.
It seems GNU ld 2.19 specific issue.
In fact, cygwin(2.20) can link ones successfully.

I had not imagined the binutils shipped with gcc-4.4 is so older!
I will try with other distros.

AFAIK this issue is only one on GNU ld 2.19.
