From 0036702555195d3fd8089577b7c1e2ce5f2ff5b1 Mon Sep 17 00:00:00 2001 From: Gaius Mulley Date: Mon, 13 Nov 2023 15:11:50 +0000 Subject: [PATCH] PR modula2/110779: Add reduced acinclude.m4 to allow interrogation of time features This patch adds libgm2/acinclude.m4 and libgm2/configure.host which are reduced versions from libstdc++-v3. They currently allow for discovering the time features available in libc and will be extended to discover availability of ieee128 long double support in the near future. These files were also added to provide the functions: GLIBCXX_CONFIGURE, GLIBCXX_CHECK_GETTIMEOFDAY and GLIBCXX_ENABLE_LIBSTDCXX_TIME called by configure.ac. libgm2/ChangeLog: PR modula2/110779 * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac: Remove newline. * libm2cor/Makefile.in: Regenerate. * libm2iso/Makefile.in: Regenerate. * libm2log/Makefile.in: Regenerate. * libm2min/Makefile.in: Regenerate. * libm2pim/Makefile.in: Regenerate. * acinclude.m4: New file. * configure.host: New file.
