+Subject: [PATCH 1/2] configure.ac: use AC_USE_SYSTEM_EXTENSIONS
+
+We use fcvt and gcvt, both of which are extensions
+guarded by GNU_SOURCE. Use AC_USE_SYSTEM_EXTENSIONS
+to ensure they're always available.
+
+Fixes a build failure on musl with Clang 15:
+```
+src/sio/sprint.c:176:15: error: call to undeclared function 'fcvt'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
+                p = (char *)fcvt( num, precision, &decimal_point, is_negative ) ;
+src/sio/sprint.c:178:15: error: call to undeclared function 'ecvt'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
+                p = (char *)ecvt( num, precision+1, &decimal_point, is_negative ) ;
+```
+
+And drop a single #define _GNU_SOURCE from signals.c, as it's
+preferable to have it consistently defined across the codebase
+where possible. We have autotools, so let's use it.
