Comment 1 Dmitry Gorbachev 2011-12-14 15:37:29 UTC 
Bug 13497: "LTO keeps unneeded functions (mingw32 target)".
Comment 2 Dmitry Gorbachev 2011-12-27 22:06:02 UTC 
Another bug: LD removes a function given as an argument to `--entry=...' option.

Symbol `_foo' gets PREVAILING_DEF_IRONLY_EXP resolution.
