Sorry for the stupidity... just found the -I<dir> option... Although it is a bit frustrating when an FFI program that used to compile stops when you add supposedly "harmless" options such as -O or -prof. Might be worth adding a section to the FFI section of the manual about using the -I<dir> flag when compiling via C, as -I<dir> is not needed when you compile with native code generation. And a mention in the FFI section that -prof and -O will change the compilation strategy from native to via-C (thus possibly requiring the addition of the -I<dir> flag) would be nice, although I realise that's duplicating information available elsewhere. (Actually, compiling via C has been valuable for me because the C compiler moaned about a foreign function being called with too few args, which was the result of an incorrect "foreign import" declaration i.e. the C compiler found a bug in my Haskell code, which the GHC native code-generator wouldn't have picked up. Plus it gives warnings on other dodgy things I'm doing. Better fix 'em...) Alistair.

The "oci.h" file in question is located in c:\orant817\oci\include, and oci.dll is located in c:\orant817\bin. When I compiled with -prof I tried adding -#include c:\orant817\oci\include\oci.h, but this produces the output below, where files included by oci.h can't be found. The oci.h file is at the root of quite a large .h include tree; do I have to specify every .h file in this tree with -#include?
