Problem with sources in multiple directories

["PAUL KOVITZ" <pkovitz@home.com>]

Hello. I am new to Source Navigator and I am having what must be a very
basic problem. I am running 4.52 Source Navigator on Windows 98 2nd edition
and the latest version of cygwin (I upgraded after I had this problem). I
have a project with sources in two separate directories as follows:
./src1/fn.h -- contains function headers for f1() and f2()
./src1/fn.c -- contains f1() and f2() definitions. includes fn.h
./src2/main.c -- contains main() definition. calls f1() includes fn.h
If I add only ./src1 to the build target, then I can compile fn.c (it won't
link because it doesn't have main).
If I add only ./src2 to the build target, then I can compile main.c (it
won't link because it doesn't have the functions in fn.c).
If I add both ./src1 and ./src2 to the build target, then fn.c does't
compile. The error message is:
make: *** No rule to make target `fn.h', needed by `fn.o'.  Stop.

I have changed the build rules so that both ./src1 and ./src2 are added
during gcc with the -I option. I thought this might be the VPATH problem I
was reading about in the archives, but upgrading my cygwin does not fix the
problem. What am I doing wrong? Any help would be greatly appreciated.
