+Subject: flopen: Add missing <fcntl.h> include
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit 993828d84ee (Add flopenat() function from FreeBSD) dropped the
+fcntl.h header. This breaks the build with musl libc:
+
+flopen.c: In function ‘vflopenat’:
+flopen.c:60:14: error: ‘O_CREAT’ undeclared (first use in this function)
+  if (flags & O_CREAT) {
+              ^~~~~~~
+
+Restore the fcntl.h header include to fix the build.
+
+Fixes: commit 993828d84eed0468c6c15b2818e534e6b134b8e4
