I think it's pretty unusual to install libraries and headers in
/usr/share, particularly in the case of libraries. gcc/linux has
conventions for this type of thing. I broke them when I installed
headers and libraries in /usr/include/w32api. I don't think we should
stray further by putting things in /usr/share.
Could Dave Korn weigh in on this?
