Commit 05a38d4c4a ("src: conditionalize / remove use of sys/ioctl.h") aimed to remove imports of ioctl.h and conditionalize them for compilation on Windows. However, the change made in virvsock.c: -#include <sys/ioctl.h> +#ifdef HAVE_SYS_IOCTL_H +# include <sys/ioctl.h> +#endif Makes the 'sc_prohibit_always_true_header_tests' rule complain about the redundancy of this test when building it on Linux. ../src/util/virvsock.c:20:#ifdef HAVE_SYS_IOCTL_H build-aux/syntax-check.mk: do not test the above HAVE_<header>_H symbol(s); with the corresponding gnulib module, they are always true make: *** [../build-aux/syntax-check.mk:1679: sc_prohibit_always_true_header_tests] Error 1 make: *** Waiting for unfinished jobs.... This patch fixes it by changing the conditional to #ifndef WIN32 instead, like the other changes made by that patch. CC: Daniel P.
