-pedantic $o -g -Wall -I. -o bar41.$o foo.c ;./bar41.$o;done
# o=''
bash: gcc-4.1-HEAD: command not found
bash: -pedantic: command not found
bash: ./bar41.: No such file or directory
# o='-O2'
bash: gcc-4.1-HEAD: command not found
bash: -pedantic: command not found
bash: ./bar41.-O2: No such file or directory
