We should make a list of D features that we can have with and 
without malloc. Then a test program that use all these feqatures.
An object file is not picked from the library if it is not used. 
Options are not needed when compiling the library.

It is ok for me and it is used in our production code that does 
not yet use D. I am still open for other solutions.
These functions should be at least extern C because library code 
written in C may use them.
