[21.4] XEmacs configure breaks early on current Linuxen

Hi, on a current (2018-12) Arch Linux installation, attempting to build XEmacs 21.4 from pkgsrc (no Arch package) fails early in configure: checking whether ln -s works... yes checking host system type... x86_64-unknown-linux XEmacs has no builtin knowledge of `x86_64' machines.

I guess not finding cpp(1) is not helpful... The pkgsrc installation uses the native compiler: % gcc --version | head -1 gcc (GCC) 8.2.1 20181127 % which cpp /usr/bin/cpp % config.log has lots of entries like [...] configure:4251: checking for tm_zone in struct tm configure:4262: cc -c -O2 -Dunix -D_FORTIFY_SOURCE=2 -I/opt/local/include -I/usr/include -I/opt/local/include/ncurses -I/opt/local/include -I/usr/include -I/opt/local/include/ncurses -I/opt/local/include -I/opt/local/include conftest.c 1>&5 In file included from configure:4254: confdefs.h:25:15: error: two or more data types in declaration specifiers #define gid_t int ^~~ confdefs.h:26:16: error: two or more data types in declaration specifiers #define mode_t int ^~~ confdefs.h:24:15: error: two or more data types in declaration specifiers #define uid_t int ^~~ confdefs.h:27:15: error: two or more data types in declaration specifiers #define off_t long ^~~~ confdefs.h:23:15: error: two or more data types in declaration specifiers #define pid_t int ^~~ confdefs.h:28:17: error: two or more data types in declaration specifiers #define ssize_t int ^~~ confdefs.h:22:16: error: duplicate 'unsigned' #define size_t unsigned ^~~~~~~~ configure: In function 'main': configure:4258:11: error: storage size of 'tm' isn't known struct tm tm; tm.tm_zone; ^~ configure: failed program was: #line 4254 "configure" #include "confdefs.h" #include <sys/types.h> #include <sys/time.h> int main() { struct tm tm; tm.tm_zone; ; return 0; } [...] where the error messages don't make any sense to me - but my autohell fu is rusty. I can provide detailed build log files, if needed. Does the above speak to anyone, and would you have a fix?
