+ Remove -lcurses from link command -- icb only needs termcap support,
and then only for the embedded readline library.
Bump the PKGREVISION to 4.
- no errno, use errno.h
- no redefinition of function parameters as local variables
[how did this ever work?!]
- malloc comes from stdlib.h
- NAME_MAX is prefered when available, it is POSIX
- strchr, strpbrk, strspn, strstr, strtol and strtoul can and
should be used from libc.
- remove tcl version of string.h, system header is good enough
(and if it doesn't have index, it would have been broken anyway)
intended transformation: use "rm" to remove an option, "rmdir" to remove
all options containing a path starting with a given directory name, and
"rename" to rename options to something else.
INSTALL -d => INSTALL_*_DIR
INSTALL => INSTALL_*
Beware that only invocations are changed that don't set special
values for owner, mode or group!
