+Subject: [PATCH] Allow avro C to be built on musl based systems.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The type `ssize_t` is defined in sys/types.h, and nowhere else
+in the musl standard C library, so it should be included for the
+compilation to succeed.
+
+This fixes several errors like:
+
+    In file included from src/generic.c:29:0:
+    src/generic.c: In function ‘avro_generic_value_new’:
+    src/avro_generic_internal.h:63:39:
+        error: ‘ssize_t’ undeclared (first use in this function);
+               did you mean ‘size_t’?
+
+Upstream-Status: Backport
+Signed-off-by: Titouan Christophe <titouan.christophe@railnova.eu>
