Comment(by simonmar):
Thanks for the patch. This hunk doesn't look right to me:
{{{
+ifeq "$(UseLibFFIForAdjustors)" "YES"
+# When we use libffi, foreign import wrappers will #include "ffi.h" so
+# we must tell the C preprocessor where it is.
+SRC_HC_OPTS += -Irts/dist/build
+SRC_CC_OPTS += -Irts/dist/build
+endif
+
}}}
(I couldn't add a comment in github, not sure why)
We should be finding `ffi.h` in the same way that we find `Rts.h`,
whatever that is. If we have to do something magic in the build system to
find `ffi.h`, won't that break when we install GHC?
Modifying `SRC_HC_OPTS` in the build system is usually not the right thing
to do - it is for `mk/build.mk` to set, with a default in `mk/config.mk`.
You'll notice that no other `.mk` file in the build system sets
`SRC_HC_OPTS` or `SRC_CC_OPTS`.
