+From c9d899c7fbf6e445b44372ba4814dc7c1b8e702d Mon Sep 17 00:00:00 2001

+Subject: [PATCH] compiler/str.h: include stdarg.h for va_list
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With some toolchains, compilation of str.c produced the following error:
+
+compiler/str.h:56:50: error: unknown type name ‘va_list’
+ int str_vaddf(struct str *v, const char *format, va_list ap) ATTR(2,0);
+ ^~~~~~~
+
+One toolchain had the following in its stdarg.h:
+"We deliberately do not define va_list when called from
+stdio.h, because ANSI C says that stdio.h is not supposed to
+define va_list."
+
+str.c includes stdio.h, but none of the prior includes result in the
+inclusion of stdarg.h. Therefore, explicitly include it in str.h to fix
+the issue on toolchains following this ANSI C rule.

Adds the c-capnproto package. This creates a C plugin for the regular capnproto capnpc compiler. It supports only serialization (no RPC). Since it depends on capnproto, the package selects capnproto and has the same requirements as capnproto. Includes a patch submitted upstream to fix a compilation error hit by some toolchains.
