DM linker vs GCC linker?

[Andrea Fontana]

This param:
--Xlinker --export-dynamic  

slows down the entire app (check() std.xml function) by 29x on test. 

Is it useful to add it on default config? Probably if you use external
dl, you should add it...

andrea at ububox:~/src/xml-test$ dmd -c test.d && gcc test.o -o testgcc2
-m64 -Xlinker --export-dynamic -Xlinker --no-warn-search-mismatch
-lphobos2 -lpthread -lm -lrt
andrea at ububox:~/src/xml-test$ time ./testgcc2 cities.xml
