The gamma launcher is used to run and debug hotspot from Visual Studio.
So removing gamma effectively kills the working environment for a number
of people that use it daily. So I am strongly against removing it.
Maybe the visual studio project generator could be updated to create a a
"launch configuration" for launching java.exe from a JDK and use the
XXaltJVM flag on to select the correct jvm.dll?
I agree that we shouldn't break the visual studio project but currently
there's nothing indicating that we can't fix it.

Most people working on Windows use Cygwin as the last resort since it
makes a lot of thing excruciatingly slow.

Chris,
Just an observation and not a review.
Looks like you're removing launcher support on Windows, but it
looks like the new hotspot.script doesn't support Windows...
Am I missing something?
Almost certainly true. Since I'm not a Windows user (and nobody near
me is one) I have no idea how people are using the gamma launcher on
Windows (or the hotspot script for that matter).
I presume most people doing debugging on the command line are already
in cygwin? But I might be wrong.

This change removes the duplicated java launcher files (which were
subject to bit-rot) and modifies the hotspot script to pick up the
libjvm in the current build directory.
The modified hotspot script works with GDB and DBX:
