Suggested by Paul Eggert in: <https://lists.gnu.org/archive/html/bug-gnulib/2025-05/msg00216.html>. * m4/stdckdint_h.m4: New file. * modules/stdckdint-h (Files): Add m4/stdckdint_h.m4. (configure.ac): Remove checks and just invoke gl_STDCKDINT_H. (Makefile.am): Replace variables set by ./configure. * lib/stdckdint.in.h: Include the compilers header if it exists. Add comment mentioning expected future standardization in C++26. (ckd_add, ckd_sub, ckd_mul): Only define if the compilers definitions do not work.
