Pretty confident - the logfile only contains `icc` calls

To be sure I used that as well. icc is being used:
[...]
customize IntelFCompiler
customize IntelFCompiler using config
icc options: '-pthread -fno-strict-aliasing -OPT:Olimit=0 -DNDEBUG -g -O3
-Wall -Wstrict-prototypes -fPIC -fPIC'
compile options: '-I/home/baecker/python/include/python2.4
-Iscipy/base/src -I/home/baecker/python/include/python2.4 -c'
icc: _configtest.c
icc: Command line warning: ignoring option '-O'; no argument required
_configtest.c(50): warning #181: argument is incompatible with
corresponding format string conversion
fprintf(fp,"#define SIZEOF_LONG_DOUBLE %d\n", sizeof(long
double));
[...]
(Note this is all with `icc -v: Version 9.0`)

With gcc version 3.3.3 (SuSE Linux)
everything compiles fine (BTW: much less warnings).
scipy.test(10,10): Ran 160 tests in 1.219s
So this looks fine!
I think that the problem is really related to icc.
Many thanks, Arnd
