+
+Instead of using #define _GNU_SOURCE in some source files which causes problems
+when building with musl as more files need the define, simply use
+AC_USE_SYSTEM_EXTENSIONS in configure.ac to get it defined globally.

+Subject: [PATCH 3/3] Rationalise includes
+
+gweb/gresolv.c uses snprintf() and isspace() so it should include stdio.h and
+ctype.h.
+
+tools/dnsproxy-test uses functions from stdio.h.
+
+musl warns when sys/ headers are included when the non-sys form should be used,
+so switch sys/errno.h and so on to errno.h.
+
+musl also causes redefinition errors when pieces of the networking headers are
+included, so remove the redundant includes.
+
+Based on work by Khem Raj <raj.khem@gmail.com>.
