Manipulating the character class table in ctype.c by hand is error prone. To ensure that typos are found quickly, add a test program and script. test-ctype checks the output of the character class macros isspace() et. al. by applying them on all possible char values and consulting a list of all characters in the particular class. It doesn't check tolower() and toupper(); this could be added later. The test script t0070-fundamental.sh is created because there is no good place for the ctype test, yet -- except for t0000-basic.sh perhaps, but it doesn't run well on Windows, yet.
