https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: mail-filter/spamassassin-4.0.0-r1 has implicit function declarations in configure logs (GCC-13-SYSTEM). Discovered on: amd64 (internal ref: gcc13_tinderbox) NOTE: (GCC-13-SYSTEM) in the summary means that the bug was found on a machine that runs gcc-13 but this bug MAY or MAY NOT BE related to the new compiler See also: https://bugs.gentoo.org/898488#c4.

Gonna' mumble to myself in here. Only section in config.log that I see which refers to "implicit": ============================================================================ configure:2499: checking for ANSI C header files configure:2524: x86_64-pc-linux-gnu-gcc -c -O2 -pipe -mtune=generic conftest.c >&5 configure:2530: $? = 0 configure:2534: test -z || test ! -s conftest.err configure:2537: $? = 0 configure:2540: test -s conftest.o configure:2543: $? = 0 configure:2632: x86_64-pc-linux-gnu-gcc -o conftest -O2 -pipe -mtune=generic -Wl,-O1 -Wl,--as-needed conftest.c >&5 conftest.c: In function 'main': conftest.c:26:7: warning: implicit declaration of function 'exit' [-Wimplicit-function-declaration] 26 | exit(2); | ^~~~ conftest.c:10:1: note: include '<stdlib.h>' or provide a declaration of 'exit' 9 | #include <ctype.h> +++ |+#include <stdlib.h> 10 | #if ((' ' & 0x0FF) == 0x020) conftest.c:26:7: warning: incompatible implicit declaration of built-in function 'exit' [-Wbuiltin-declaration-mismatch] 26 | exit(2); | ^~~~ conftest.c:26:7: note: include '<stdlib.h>' or provide a declaration of 'exit' conftest.c:27:3: warning: incompatible implicit declaration of built-in function 'exit' [-Wbuiltin-declaration-mismatch] 27 | exit (0); | ^~~~ conftest.c:27:3: note: include '<stdlib.h>' or provide a declaration of 'exit' configure:2635: $? = 0 configure:2637: ./conftest configure:2640: $? = 0 configure:2655: result: yes ============================================================================ From configure itself: ============================================================================ if test $ac_cv_header_stdc = yes; then # /bin/cc in Irix-4.0.5 gets non-ANSI ctype macros unless using -ansi. if test "$cross_compiling" = yes; then : else cat >conftest.$ac_ext <<_ACEOF /* confdefs.h. */ _ACEOF cat confdefs.h >>conftest.$ac_ext cat >>conftest.$ac_ext <<_ACEOF /* end confdefs.h. */ #include <ctype.h> #if ((' ' & 0x0FF) == 0x020) # define ISLOWER(c) ('a' <= (c) && (c) <= 'z') # define TOUPPER(c) (ISLOWER(c) ?

Is it a standard autoconf test, like a part of AC_HEADER_STDC?
That one is a standard autoconf test, so eautoreconf should fix it (we have it patched in Gentoo & the next autoconf release fixes it).

Word is that the standard test is fixed in the next autoconf release, so this may not need to stick around for too long.
