I've found an obvious bug in git-svn during this whole process, and I'd like
to file a helpful bug report.  If you can spare a minute or two to give me
your educated guess about it, I'd be very grateful.

The clone I made of your svn repo using git-svn won't compile, and to me the
error message doesn't make any sense:

kBuild: Compiling RuntimeR3 - /U/wa1ter/src/vbox.git/src/VBox/Runtime/common/misc/buildconfig.cpp
/U/wa1ter/src/vbox.git/src/VBox/Runtime/common/misc/buildconfig.cpp: In function ‘uint32_t RTBldCfgRevision()’:
/U/wa1ter/src/vbox.git/src/VBox/Runtime/common/misc/buildconfig.cpp:39: error: ‘ev’ was not declared in this scope

The source file is identical between your svn repo and my git-svn repo, so it
seems git-svn has messed up some other file(s) somewhere.

Any wild guesses about where I should look in my git-svn repo to find the real
source of the breakage?

Many thanks for your help!
