I just found that the intel compiler (icc 9.0)
also supports compiler warnings for portability
problems.
For the file
#include <sys/types.h>
int foo(size_t x)
{
return x;
}
it says (with -Wall)
a.c(3): remark #1418: external definition with no prior declaration
int foo(size_t x)
^
a.c(5): remark #1682: implicit conversion of a 64-bit integral type to a
smaller integral type (potential portability problem)
return x;
^
If you just want the latter warning, pass -Wp64.

P.S. In case you want to install it on a Debian AMD64 system,
here is the procedure:
1. register at
https://registrationcenter.intel.com/EvalCenter/EvalForm.aspx?ProductID=408
2. download and unpack the l_cc_c_9.0.030 tarfile.
3. don't try alien, it won't work.
4. don't try the Intel install.sh, it won't work
(atleast, it didn't work for me)
5. Instead, install with 'rpm -i --nodeps *.em64t.rpm'
6. edit /opt/intel/cce/9.0/bin/icc, replacing all
occurrences of <INSTALLDIR> with /opt/intel/cce/9.0
7. Put the *.lic file that Intel sent you into
/opt/intel/cce/9.0/bin
