------- Comment #1 from burnus at gcc dot gnu dot org  2008-06-15 08:04 -------
doing   isdigit ((int) *p)  works; however, I'm not sure this is the right
method - and I wonder why there is this warning only on sparc-solaris8 and not
on other systems - "isdigit" takes on all systems an integer. Additionally the
"array subscript" in the error message is really strange.

You should use isdigit ((unsigned char) *p).  The argument of all ctype
functions must be in the range of unsigned char or EOF.

Jerry, since you are working on I/O patches currently, can you include a fix
for this problem?

None of the proposed type casts fix this problem.  Requires some configury
repair work.
