I'm working with Dan's bootVM to get to run on Windows, and have been
thinking about the use of -fpack-struct vs #pragm pack() vs just not
packing and writing code that is a little slower, and a little more
verbose, but seemingly more robust and maintainable due to less
information about context needed to avoid surprises.
I've reconfirmed that packing structs is deadly when you want to call
into standard libs
struct stat foo;
stat("foo.txt", &foo);
does some bizarre things :)
So how do people deal with this these days? I know fashions change,
and I haven't done C in anger for > 6 years... (I still have the
shakes when looking at it - I'm past the screaming stage...)

hi,
We should compile the code using the same C flags that the libc uses.
Parameter marshalling is another source of problems: if we want to
optimize
our C code for speed (parameters passed through registers), we will
have to recompile the libc.
