ChangeLog, e2image.c, mke2fs.c, mklost+found.c, tune2fs.c, util.c, uuidgen.c:
  e2image.c, mke2fs.c, mklost+found.c, tune2fs.c, util.c, uuidgen.c: Fix
  	gcc -Wall complaints, including one bug in tune2fs caused by a block
  	automatic shadowing version of the variable we really wanted to use,
  	which broke the logic testing to see if the filesystem was mounted.
ChangeLog, MCONFIG.in:
  (gcc-wall-new): Added new target which forgoes the make clean so we
  	only check the newly modified .c files.
