RFA: PR 66655: Use COFF/PE weak symbols

Hi Jeff,

Thanks - committed.

dg-additional-sources is the command that you are thinking about.


The attached patch adds the test derived from the BZ.  There is one 
small problem - I could not find a way to stop the additional source 
file from being compiled as a test on its own.  When I investigated 
however it seems that is a common problem for all tests that use 
additional source files, so I do not think that it is a big issue.

Tested with no regressions on an x86_64-pc-linux-gnu toolchain.

OK to apply ?

Cheers
   Nick
