configure.ac:55: warning: The macro `AC_PROG_CC_STDC' is obsolete.
I reproduced these warnings; they come from Autoconf 2.71. You can
ignore them, or you can update to the latest coreutils on Savannah,
where I installed some patches (attached) to silence these.
doc/local.mk:19: installing 'build-aux/mdate-sh'

doc/local.mk:19: error: required file 'build-aux/texinfo.tex' not found

I don't observe this problem. gnulib-tool sets up a symlink that works:
$ ls -l build-aux/texinfo.tex gnulib/build-aux/texinfo.tex
lrwxrwxrwx 1 eggert eggert 31 Apr 26 23:59 build-aux/texinfo.tex ->
../gnulib/build-aux/texinfo.tex
-rw-rw-r-- 1 eggert eggert 379274 Apr 26 23:56 gnulib/build-aux/texinfo.tex
If you still observe a problem with a fresh build from scratch, please
investigate why gnulib-tool isn't setting up that link for you

* src/csplit.c (load_buffer):
* src/pinky.c (create_fullname):
Use intprops-based checks rather than xalloc_oversized,
since Gnulib xalloc.h no longer includes xalloc-oversized.h.

Do not require AC_ISC_POSIX, which became obsolete in 2006.
Use AC_LINK_IFELSE instead of AC_TRY_LINK.
