----------------------------------------
Bug #7960: Ruby fails to build static under mswin linker error: multiple definitions of _Init_ext
https://bugs.ruby-lang.org/issues/7960

Author: Ryexander (Benjamin Powers)
Status: Open
Priority: Normal
Assignee: 
Category: build
Target version: 2.0.0
ruby -v: 1.9.3


after the depend errors were fixed I obtained r39490 and attempted to build it

after nearly completing it failed with 

ruby200.dll : fatal error LNK1169: one or more multiply defined symbols found

searching through the output found only one line with a "already defined"

ruby200-static.lib(dmyext.obj) : error LNK2005: _Init_ext already defined in ext
init.obj

attached is the full output of the configure.bat and nmake commands run with arguments
