[Insight-users] Compilation problem

[Sandhitsu Das]

This most probably has to do with gcc 3.4 -- I encountered the same  
problem. There are other parts of ITK code that also breaks with gcc  
3.4 with the same error. The workaround I found is to use the - 
fpermissive compiler flag which converts this error to a warning.

This is discussed here (search for "changes meaning of"):
