+
+After libcnetinet_HEADERS was set to sctp.h.in, netinet/sctp.h can
+no longer be installed into ${includedir}.
+
+Since "AC_CONFIG_HEADERS([src/include/netinet/sctp.h])" is already
+added into configure.ac, there's no need to generate sctp.h by
+automake.
+
+So we simply set libcnetinet_HEADERS back to sctp.h.

+Subject: [PATCH] patch rktio_process for "/bin/sh" on Guix
+
+Racket provides the functions `system` and `process`,
+which execute shell commands using `sh` (or `cmd` on Windows).
+Racket assumes that `sh` can be found at "/bin/sh",
+which is not necessarily true on Guix.
+
+This patch adds a special case for "/bin/sh" to `rktio_process`,
+the C function that implements the core of `system`, `process`,
+and related Racket functions.
+
+Guix should enable the special case by defining the C preprocessor
+macro `GUIX_RKTIO_PATCH_BIN_SH` with the path to `sh` in the store.
+If:
+
+    1. The `GUIX_RKTIO_PATCH_BIN_SH` macro is defined; and
+
+    2. `rktio_process` is called with the exact path "/bin/sh"; and
+
+    3. The path specified by `GUIX_RKTIO_PATCH_BIN_SH` does exists;
+
+then `rktio_process` will execute the file specified
+by `GUIX_RKTIO_PATCH_BIN_SH` instead of "/bin/sh".
+
+Compared to previous attempts to patch the Racket sources,
+making this change at the C level is both:
+
+    - More comprehensive: it catches all attempts to execute "/bin/sh",
+      without having to track down the source of every occurance; and
+
+    - Less intrusive: by guarding the special case with a C preprocessor
+      conditional and a runtime check that the file in the store exists,
+      we make it much less likely that it will "leak" out of Guix.
