However, the root cause is that the HAVE_EXP10* macros are never defined. While I was at it, I checked for other cases where the code uses HAVE_* macros that are missing from config.h.in. This patch adds the missing checks, changes the configure checks where the names don't match what's used in the code, or corrects the code to use the right names. So far tested on sparc64-unknown-linux-gnu by building libgm2 (32 and 64-bit) and running the gm2 tests. 2024-02-12 Rainer Orth libgm2: PR modula2/113888 * configure.ac (GM2_CHECK_LIB): Rename gettimeofday guard to HAVE_GETTIMEOFDAY. (GM_CHECK_LIB): Check for settimeofday. (GM2_CHECK_LIB): Check for exp10, exp10f, exp10l in libm. (AC_CHECK_DECLS): Check for getenv. * configure, config.h.in: Regenerate. * libm2pim/dtoa.cc: Rename , guards to HAVE_STRINGS_H, HAVE_STRING_H. * libm2pim/ldtoa.cc: Likewise.
