ml.exe working only in x86 tools, not in x64

[adamantinum]

I really appreciate your work and I find your tool very useful.
Building some stuff, I noticed that – as per the title – I cannot use ml.exe from x64 tools, it just return to prompt doing nothing. The same thing happens running ml64.exe from x86 tools.

sh-5.3$ /opt/msvc/bin/x64/ml.exe
sh-5.3$ /opt/msvc/bin/x64/ml64.exe

Run "ML64 /help" or "ML64 /?" for more info
