I will add a real-world use case. Lets say that I am the author of a shared
library and that today I wish to provide my client, AnApp, with MyLib version 1.
I will also need to provide my clients with updated

Maybe I should rephrase my concern as the following question. Suppose a gcc
user is building an application and some shared libraries that depend on third
party libraries. Under what circumstances can he

Suppose for a moment that the boost authors can be convinced to add a bunch of
GCC-specific pragmas to their code. Would the problem then be solved? What if
a client is using a third party library (maybe a

Sorry, I was a bit sloppy--I didn't remove all intermediate layers from my test
environment. I will explore this further. In any case, if I explicitly invoke

Actually, I'll just paste the darwin test case here. On this platform, libstdc++
is a sharedlib. The following code:
###
#include

int main (int argc, char * const argv[]) {
