...a veeery old bugreport :]
Thanks a lot for reporting and sorry for no_reply

Right now I'm able to build master branch on NetBSD 10.0 (x86_64 and aarch64).
It seems clang on NetBSD 9.x doesn't support "C17" (see Makefile.in), so just changing it back to "C11" will fix it.

I will close it now.

I tried compiling the latest git source on NetBSD 4.0, and there was an error regarding getutent():

gcc -c -I. -I.  -DETCSCREENRC='"/usr/pkg/etc/screenrc"' -DSCREENENCODINGS='"/usr/pkg/share/screen/utf8encodings"' -DHAVE_CONFIG_H -DGIT_REV=\""`git describe --always 2>/dev/null`"\" \
             -g -O2 utmp.c
utmp.c:92: error: static declaration of 'getutent' follows non-static declaration
/usr/include/utmp.h:66: error: previous declaration of 'getutent' was here
utmp.c:93: error: static declaration of 'endutent' follows non-static declaration
/usr/include/utmp.h:67: error: previous declaration of 'endutent' was here
utmp.c:95: error: static declaration of 'setutent' follows non-static declaration
/usr/include/utmp.h:65: error: previous declaration of 'setutent' was here

Apparently configure thinks that there is no getutent(), but there is, in <utmp.h> It is just the configure check which is incorrect. It fails because it has an un#defined name. From config.log:

configure:5286: checking getutent...
configure:5311: gcc -o conftest -g -O2   conftest.c -lcurses  >&5
conftest.c: In function 'main':
conftest.c:53: error: 'DEAD_PROCESS' undeclared (first use in this function)
conftest.c:53: error: (Each undeclared identifier is reported only once
conftest.c:53: error: for each function it appears in.)
configure:5311: $? = 1

It seems that utmp.c actually uses DEAD_PROCESS, but I suppose that will have to be tested separately.

Pkgsrc has some patches in this area: patch-{ai,aj,al,am,an}. The other patches are probably also worth to be included.

See here for the mentioned patches: http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/misc/screen/patches/
