Environment: NetBSD petaure.lan 5.99.39 NetBSD 5.99.39 (PETAURE) #10: Sat Nov 6 20:30:46 CET 2010 njoly@petaure.lan:/local/src/NetBSD/obj.amd64/sys/arch/amd64/compile/PETAURE amd64

pcc 0.9.9 for x86_64-unknown-netbsd5.99.39, njoly@petaure.lan Sun Nov 7 11:29:56 CET 2010

The following piece of code fails to compile when #include_next directive is located within a conditional
which is not active, and succeed otherwise.

njoly@petaure [~]> cat include.c
#ifdef USE_NEXT
#include_next <stdlib.h>

int main() { return 0; }

njoly@petaure [~]> pcc -UUSE_NEXT include.c; echo $?
/usr/include//stdlib.h:329: error: unterminated conditional
njoly@petaure [~]> pcc -DUSE_NEXT include.c; echo $?
njoly@petaure [~]> pcc -E -UUSE_NEXT include.c
# 1 "include.c"

# 1 "/usr/include//stdlib.h"
/usr/include//stdlib.h:329: error: unterminated conditional

Fixed now. Had forgotten to check the false flag.
