For convenience I used one test-project with several targets so that all
test apps are build at once. Two for each library to test: test.c and
-gc_app.cc. When I was satisfied that the libraries were ok. I put the
+gc_app.cc. When I was satisfied that the libraries were OK. I put the
libraries + gc.h + the c++ interface-file in a folder that I then put into
the MSL hierarchy so that I don't have to alter access-paths in projects
that use the GC.
but on some platforms it may require assembly code, or just
tweaking of conditional compilation tests.
