--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2010-10-12 08:15:40 UTC --- I have also been hit by this pr, but only for gcc, g++, and gfortran. All the other tests have accepted RUNTESTFLAGS="--target_board 'unix{-m32,}'". > What is SHELL set to in gcc/Makefile? I don't know if this answer the question, but I call make from tcsh. > Does it work on your system to > use this instead (in a tree with the patch not reverted): > make -k check RUNTESTFLAGS='--target_board=unix"{-m32,-m64}"' As advised on IRC, RUNTESTFLAGS='--target_board=unix\{-m32,-m64\}' works.
