- The intel compiler can't compile the kernel. (This is on the intel homepage)
- Many GNU programs use GNU specific compiler extensions that don't work
with the Intel compiler.
- Several command line options of the compilers differ - this means
several configure/make scripts might not work as supposed or won't work
at all.
- The C++ ABI is incompatible -> you can't link C++ libraries compiled
with the GNU compiler with code compiled with the Intel compiler.
This is a pretty hard limitation - for example for KDE stuff
This are just some things that came up to my mind quickly... ;)
