Fix in MKC_CHECK_PROTOTYPES. The problem was it says "found" for
undeclared prototypes.
All FEATURES now check for _MKC_CHECK_<xxx> define. A check for
this define guarantees that #include <mkc_XXX.h> are not used
without appropriate MKC_FEATURES += <xxx> in Makefile.
New publicly available mkc.conf.mk header was introduced. With a
help of it one can implement custom "FEATURES".
MKC_CHECK_HEADERS, MKC_CHECK_HEADER_FILES, MKC_CHECK_DEFINES,
MKC_CHECK_TYPES, MKC_CHECK_VARS, MKC_CHECK_MEMBERS,
MKC_CHECK_FUNCS<n>, MKC_CHECK_PROTOTYPES, MKC_CHECK_SIZEOF and
MKC_PROTOTYPE_HEADERS.<name> now accepts a list of comma-separated
headers for checking at once.
For example, on NetBSD sys/fts.h requires preceding sys/types.h and
sys/stat.h. So, now we can write
MKC_CHECK_HEADERS = sys/types.h,sys/stat.h,fts.h
MKC_CHECK_FUNCS<n>: new variable MKC_FUNC_OR_DEFINE.<func> was introduced.
With a help of it one can check for
function declaration of equivalent define.
mkc_imp.conf-final.mk: duplicated entries are not added to CPPFLAGS,
CFLAGS, LDADD and SRCS.
Man page for mkc_check_decl, mkc_check_sizeof and mkc_check_headers
were updated.
mkc.minitest.mk: new variable MKC_DIFF was introduced for diff(1)
command.
mkc_check_decl: new check type funcordefine was introduced.
Improvements and minor fixes in regression tests and examples.
This release was sucessfully tested on FreeBSD-11.1, diverse
glibc-based Linuxes, NetBSD-8.99, OpenBSD-6.4 and SunOS-5.11.
Deprecated features were removed: DPLIBS and PKG_CONFIG_DEPS variables,
builtin "endianess".
