gcc options: '-pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall - 
Wstrict-prototypes -fPIC'
compile options: '-Ibuild/src/scipy/base/src -Iscipy/base/include - 
Ibuild/src/scipy/base -Iscipy/base/src -I/usr/include/python2.4 -c'
gcc: scipy/base/src/multiarraymodule.c
In file included from scipy/base/src/multiarraymodule.c:44:
scipy/base/src/arrayobject.c: In function ‘parse_subindex’:
scipy/base/src/arrayobject.c:1368: warning: passing argument 4 of  
‘slice_GetIndices’ from incompatible pointer type

After fixing this (revision 1447; 'stop' before this warning was  
declared int, not intp),  everything seems to work fine on an Athlon  
64 running Linux.
