[racket] MSB8012 conversion error compiling Racket with VS2010

After converting solution files from VS2008 to VS2010, I get errors like

MSB8012: $(TargetName) ('libmzgc') does not match the Linker's OutputFile  
property value '..\..\..\lib\libmzgcxxxxxxx.dll' ('libmzgcxxxxxxx') in  
project configuration 'Release|x64'. This may cause your project to build  
incorrectly. To correct this, please make sure that $(TargetName) property  
value matches the value specified in %(Link.OutputFile).">


in the conversion log file and build.bat (from Racket-5.2.1\src\worksp)  
gives errors building racket.sln

The build output for project racket is:
