# String library.

# Configuration settings:  how should "size_t", "void *", "const" be written?
# "size_t" is what's needed to hold the result of sizeof; beware of problems
# with compatibility here, because X3J11 uses this for e.g. the third
# argument of strncpy() as well.  You may need to make it "int" even if
# this is a lie.  "void *" is the generic pointer type, "char *" in most
# existing implementations.  "const" is the keyword marking read-only
# variables and parameters, unimplemented in most existing implementations.
# These things need to be defined this way because they must be fitted into
# both the .h files and the .c files; see the make instructions for string.h
# farther down.

# Things you might want to put in CFLAGS or LINTFLAGS.
# -DCHARBITS=0377		Required if compiler lacks "unsigned char".
# -Dvoid=int			Required if compiler lacks "void".
# -DUNIXERR			Unix-like errno stuff, can test strerror().
# -DBERKERR			Like UNIXERR but for Berklix (4BSD).
# -I.				string.h from here, not /usr/include.
