An alternative would be to have multiple tests in the same file, but the 
actual source code for the tests in string literals. Then the testing 
framework can write temporary files with the content from the string 
literals and run the actual compilation on those temporary files.

I think that will work pretty good as long as the code inside the string 
literals are fairly short.

Another advantage would be that any specific compiler flags that are 
required for a given test can be passed as a separate argument instead 
of being inline in the source code as a comment.
