Comment (by dekarl):

 Are you trying to work around a broken compiler?

 According to GCC's documentation (at
 https://gcc.gnu.org/onlinedocs/gccint/WHOPR.html ) the whole program
 optimization / link time optimization is supposed to work with C++
 programs using shared libraries with inline functions in headers. So to me
 this is clearly a bug in their compiler / linker.

 The referenced GCC bug (at
 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63745 ) appears to state the
 opposite in contradiction with that documentation.

 I'm happy to apply a patch that moves the relevant function's
 implementation from the header to the implementation file if that helps
 Gentoo users.
