Ok, the following alias ought to work:

alias tsize "(cd $HOME ; echo '#include <sys/stat.h>\
main(argc,argv) int argc;char **argv;{int t=0;struct stat s;\
while(--argc){stat(*(++argv),&s);t+=s.st_size;}\
printf("%d",t);}' >foo.c ; cc -o foo foo.c) ; $HOME/foo"

A bit slow for those small jobs but if you're talking Gb files it'll
work great :-).
