I have just tested with a fresh clone and cannot reproduce this issue.  I 
suspect the problem is somehow unique to your clone.  I suggest creating a new 
one and see if the problem persists.

Thanks for reporting this so quickly, though; that would be a problem if it 
were common =]

I can reproduce it with clean copy ...

Can anyone else reproduce this issue?  I need to know how prevalent this 
problem is, if it is serious enough to justify creating a new release for.

Sounds like BOM (Byte Order Mark) at the beginning on some files is screwing 
things up on Mac. I suspect the reason why we never caught it has something to 
do with gcc version; bignikita here appears to be using gcc 4.0 whereas I use 
gcc 4.2.

I can't reproduce this using:
 * i686-apple-darwin10-g++-4.2.1 
 * Darwin Kernel Version 10.4.0; root:xnu-1504.7.4~1/RELEASE_I386 i386

Maybe its due to using GCC 4.0?

I found two files that have BOM:
src/unittest-cpp/UnitTest++/UnitTest++.vsnet2005.sln
examples/FBTestPlugin/FBTestPluginAPI.cpp

Removed it from the .cpp file (the .sln file is not used in Firebreath build 
and Visual Studio probably likes BOMs):

Thanks, Kalev.  We'll put that in the nightly and wait to put out a release to 
see if any more bugs surface or if more people notice, since it only affects a 
small percentage of our userbase.

thanks for catching that, Nikita, and Kalev for doing the fix.

I can confirm that this issue affects system version gcc-4.0. With gcc-4.2 
compilation is successful
