I've just quickly checked the aspectc++ source code and found out the
problem is in there, and as such this removal request is not warranted.
All struct flock initializers in (at least) Puma/src/basics/SysCall.cc
are bogus, as it assumes the layout of the struct flock whose members
are explicitly defined as not having a specific order. The code should
switch to use named initializers or simple member assignments [0]. I've
not checked or tested if there's other portability issues though.
[0]
struct flock fl = { .l_type = A, .l_whence = B, ... };
or
struct flock fl;
fl.l_type = A;
fl.l_whence = B;
...
