Yes... I guess what made this a "boost issue" is that boost was the only
library we didn't bundle at the time.

Which would require people to know what gcc version their distro is
using. This seems reasonable to expect of people coding in C or
C++, but what of everyone else (particularly if they can't do
"gcc --version" because it isn't installed)?

Do you know of a way to detect at runtime which compiler version was
used for the libraries?
