+'install-bin' installs minilzip and its man page again.
-It has been documented in the manual that it is the responsibility of the
-program using lzlib to include before 'lzlib.h' some header that declares
-the type 'uint8_t'. (Reported by Michal Górny).
-
-The variable MAKEINFO has been added to configure and Makefile.in.
-
-It has been documented in INSTALL that when choosing a C standard, the POSIX
-features need to be enabled explicitly:
- ./configure CFLAGS+='--std=c99 -D_XOPEN_SOURCE=500'
