[phobos] std.complex not compiled into phobos.lib on Windows

[Lars Tandle Kyllingstad]

Based on the following D.learn thread it would appear that std.complex
isn't compiled into phobos.lib on Windows:

I have noted that complex.d is missing from the SRCS variable defined at
lines 97-137 of win32.mak, and I assume that's the cause of the problem.

However, I am completely unable to get Phobos to compile on Windows so I
can't know for certain whether adding it fixes the problem.  (Phobos
won't build without druntime, and apparently I can't build druntime
without some 'masm386' program which I don't have.)

Can someone confirm that adding complex.d to SRCS fixes the issue?
