+    <youpi> braunr: btw, we are missing the symbol in mach/Versions
+    <braunr> youpi: what symbol ?
+    <youpi> so the libc-provided RPC stub is not available
+    <youpi> mach_printf
+    <youpi> -f
+    <braunr> it's a system calll
+    <braunr> not exported
+    <youpi> s/RPC/system call/
+    <braunr> that's expected
+    <youpi> libc does provide stubs for system calls too
+    <braunr> yes but not for this one
+    <youpi> I don't see why we wouldn't want to include it
+    <youpi> ?! it does
+    <braunr> it's temporary
+    <braunr> oh
+    <braunr> there must be automatic parsing during build
+    <youpi> sure
+    <braunr> nice
+
+    <braunr> youpi: if we're going to make this system call exported by glibc,
+      i should change its interface first
+    <braunr> it was meant as a very quick-and-dirty hack and directly accesses
+      the caller's address space without going through a special copy-from-user
+      function
+    <braunr> not very portable
