[gmx-users] gromacs 3.3 build on x86_64

Hi Reinhold,

First try to compile this with gcc, and if that doesn't work either  
report back with your operating system and icc version.

Well, they are available, but we cannot use them since the compiler  
issues a fatal error when we include the headers.

If you really want icc you might want to try and compile the code on  
a EM64t pentium - I can imagine Intel doesn't exactly care about bugs  
on AMD processors :-)

Cheers,

Erik
