I managed to reproduce the problem in Gnulib by artificially pretending to 'configure' that clang's stdint.h was busted, using './configure gl_cv_header_working_stdint_h=no'. I installed a fix for the problem into Gnulib here: http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=705764b377ebeef7bdba1a87fafd99cd56b6f3c9 I ran 'admin/merge-gnulib' to propagate the fix into emacs-25, and then merged emacs-25 into master using the procedure described in 'admin/notes/git-workflow'. Please give this a try on your setup. Do a 'make clean' before running 'make'. If 'make' is still building lib/stdint.h, please investigate why './configure' decides that clang's stdint.h is buggy.
