Versions of gcc are never (much) dependent on kernel versions.  They  
are rarely dependent on glibc versions, and loosely dependent on  
binutil versions.  For binutils dependencies, you'd want to ask on a  
binutils list, though, doubt you'd have to worry much about it, as  
long as you aren't trying to compile with gcc-1.27 or something weird  
like that.  For glibc, you'll want to consult it's documentation and  
be sure to use a recommended gcc version, same with the kernel.

Bugs.

No.

Yes.
