Fresh svn checkout of MIDAS does not build on Fedora 5, I get this error:

make: *** [linux/lib/odb.o] Error 1
If I compile odb.c without "-O2", the rest of MIDAS builds without any more errors.
The observed warnings are (I do not know what they mean):
warning: dereferencing type-punned pointer will break strict-aliasing rules
warning: missing sentinel in function call (Cannot do without sentinels, eh?)
warning: pointer targets in passing argument 3 of 'getsockname' differ in signedness
warning: non-local variable '<anonymous struct> out_info' uses anonymous type
The "invalid lvalue" errors seem to have been successfully vanquished.
