Hey all, I've got an autoconf test which includes a header file from the source tree are configuring. This sort of break VPATH builds, since this: configure:17782: gcc -std=gnu99 -o conftest conftest.c -lm >&5 conftest.c:29:58: error: libmemcached/memcached/protocol_binary.h: No such file or directory Obviously would need a -I${top_srcdir}. I'm fine with hacking that in to the test - except there doesn't seem to be an available autoconf variable I can use to fill in the value of top_srcdir in that context. Is there a way to deal with this in general that I'm missing?
