although on re-reading [1],i have serious doubts whether there is any
safe way:

which i translate to: if any external happens to load a library (e.g.
"msvcrt.dll"), then all externals loaded afterwards and depending on a
library of the same name are doomed to use the first "msvcrt.dll".

which is of course similar on unix...but there we typically have
soversions encoded in the filename which will help resolve this issue.
