Tangobos: Symbol undefined when compiling with -g

[Simen Haugen]

I just tried tangobos in an effort to use both enki and minid. In release 
mode, everything works, but when I try to compile in debug info I get symbol 
undefined errors:

..\obj\nsconv\debug\math2.obj(math2)
 Error 42: Symbol Undefined _D3std4math3tanFeZe
..\obj\nsconv\debug\math2.obj(math2)
 Error 42: Symbol Undefined _D3std4math4tanhFeZe

 Error 42: Symbol Undefined _D3std4math3powFeeZe
..\obj\nsconv\debug\conv.obj(conv)
 Error 42: Symbol Undefined _D3std4math5isnanFeZi
--- errorlevel 6


Any idea how this can be fixed?
