+Subject: [PATCH] include unistd for close declaration
+
+When using gcc-14 the compilation fails with the following error
+message:
+
+```
+close.c: In function 'EIBClose':
+close.c:38:3: error: implicit declaration of function 'close'; did you mean 'pclose'? [-Wimplicit-function-declaration]
+   38 |   close (con->fd);
+      |   ^~~~~
+      |   pclose
+openlocal.c: In function 'EIBSocketLocal':
+openlocal.c:57:7: error: implicit declaration of function 'close'; did you mean 'pclose'? [-Wimplicit-function-declaration]
+   57 |       close (con->fd);
+      |       ^~~~~
+      |       pclose
+make[6]: *** [Makefile:611: close.lo] Error 1
+```
+
+This patch include <unistd.h> to include the declaration of close.
