How to use protoc on Windows?

This is a bug in protoc 2.0.0 which will be fixed in 2.0.1... if only I
could get this ridiculous Maven issue sorted out and release the thing. :/
The problem is that protoc interprets everything before the colon as a
generator parameter, which doesn't work when using an absolute path on
Windows. As a work-around, if the working directory is on the same drive as
the target, then you can omit the drive letter, e.g.:

protoc --java_out=\foo\bar

When I try to compile .proto file into dir with absolute path it
protoc --java_out=C:\work Some.proto
protoc --java_out=C:/work Some.proto
protoc --java_out=file://C:/work Some.proto
protoc --java_out=file:///C:/work Some.proto
How to specify absolute path for output?
Another issue is with specifying path to .proto file in windows format
using "\" as separator. It generates uncompilable code because java
throw new RuntimeException(
"Failed to parse protocol buffer descriptor for " +
"\"proto\Some.proto\".", e); // <--- invalid escape char error
here
I use ProtocolBuffers 2.0beta built on Windows using Cygwin gcc.

Vladimir
