Merge r1543147 and r1543149 from trunk:

fix versioninfo fields for abs.exe

Workaround issue with defining a preprocessor symbol to a string value
with embedded blanks.

The extra, escaped quoting in the original version is required for passing 
the definition over the command-line, but it broke Visual Studio builds.

For now, avoid the extra quoting when generating for Visual Studio.
