If you really want to --export-all in C++, this is a workaround.
Create a def with dlltool:
 dlltool --export-all --output-def foo_.def --dllname foo.dll *.o

Then look at the def file.  Do you still really want to export-all?

To use that def file with ld -shared you need to get rid of the
comments (demangled names) 
cut does the job:
  cut -d ';' -f 1 foo_.def >foo.def

Cheers
