I experienced a build failure during build extension library with trunk on Windows.

	make[2]: Entering directory `/c/work/ruby-2.1.0-r43936/ext/bigdecimal'
	generating bigdecimal-i386-mingw32.def

I found the cause of this error is mkmk failure.
Here is a part of mkmf.log

	Cannot create temporary file in C:\Users\??���?AppData\Local\Temp\: Invalid argument


The TEMP environment varable is
	
	C:\work\ruby-2.1.0-r43936>set TEMP
	TEMP=C:\Users\������\AppData\Local\Temp

It seems that miniruby cannot handle encoding properly.
	
	C:\work\ruby-2.1.0-r43936>miniruby -ve "p ENV['TEMP']"
	ruby 2.1.0dev (2013-11-30 trunk 43936) [i386-mingw32]
	"C:\\Users\\\xED\x9D\xAC\xEC\x84\xAD\\AppData\\Local\\Temp"

	C:\work\ruby-2.1.0-r43936>miniruby.exe -ve "p ENV['TEMP'].encoding"
	ruby 2.1.0dev (2013-11-30 trunk 43936) [i386-mingw32]
	#<Encoding:ASCII-8BIT>	
	
Whereas, the final ruby can handle encoding properly.

	C:\work>ruby -ve "p ENV['TEMP']"
	ruby 2.1.0dev (2013-11-30 trunk 43923) [i386-mingw32]
	"C:\\Users\\������\\AppData\\Local\\Temp"	

	C:\work>ruby -ve "p ENV['TEMP'].encoding"
	ruby 2.1.0dev (2013-11-30 trunk 43923) [i386-mingw32]
	#<Encoding:CP949>
