Unfortunately, that flag is not present in GCC 4.4.7:

Linux sciprog2.ceas bacon ~ 405: (pkgsrc): gcc -Wno-error=unused-result 
junk.c
cc1: error: -Werror=unused-result: No option -Wunused-result

Linux sciprog2.ceas bacon ~ 408: (pkgsrc): 
Pkgsrc/pkg-2017Q1/gcc49/bin/gcc -Wno-error=unused-result junk.c
Linux sciprog2.ceas bacon ~ 409: (pkgsrc):

It would have been a nice solution...
