+Subject: [PATCH] fix getopt handling of ':' modifier for multibyte option
+ characters
+
+the previous hard-coded offsets of +1 and +2 contained a hidden
+assumption that the option character matched was single-byte, despite
+this implementation of getopt attempting to support multibyte option
+characters. this patch reworks the matching logic to leave the final
+index pointing just past the matched character so that fixed offsets
+can be used to check for ':'.

+Subject: [PATCH] don't fail posix_spawn on failed close
+
+the resolution of austin group issue #370 removes the requirement that
+posix_spawn fail when the close file action is performed on an
+already-closed fd. since there are no other meaningful errors for
+close, just ignoring the return value completely is the simplest fix.

+Subject: [PATCH] use direct syscall rather than write function in posix_spawn
+ child
+
+the write function is a cancellation point and accesses thread-local
+state belonging to the calling thread in the parent process. since
+cancellation is blocked for the duration of posix_spawn, this is
+probably safe, but it's fragile and unnecessary. making the syscall
+directly is just as easy and clearly safe.

+Subject: [PATCH] don't shadow functions with macros in C++
+
+C++ programmers typically expect something like "::function(x,y)" to work
+and may be surprised to find that "(::function)(x,y)" is actually required
+due to the headers declaring a macro version of some standard functions.
+
+We already omit function-like macros for C++ in most cases where there is
+a real function available. This commit extends this to the remaining
+function-like macros which have a real function version.
