I don't know about /usr/lib/mingw specifically, but I have found that gcc
3.2.2 aligns doubles only to long boundries where as the gcc shipped with
Cygwin aligns them to double boundries.
This makes 3.2.2 broken for anything passing structures with doubles
between objects compiled with different compilers, including, I believe,
anything that shipped with Cygwin.
I would also like to get 3.2.2 working as I am trying to add DWARF2
debugging support. Any comments about this issue would be appreciated.
Thanks.
