Hi all,

I'm having some problems with implicit dependencies not functioning properly with .c files. The system does not appear to detect changes in header files, though works just fine for c++ code. I've set up a small canonical example of the problem extracted from the larger project I am working on. Mydirectory structure looks like this:

Root/
jamfile
project-root.jam (empty)
Code/
foo.h
foo.c
jamfile

The contents of Root/jamfile are:

variant _debug : debug :
<link>static
<link-runtime>static
<define>RWDEBUG
<define>LFPDEBUG
<define>VC_DEBUG
<define>_DEBUG
;

project jamtest
: requirements
<include>.
<include>"./Code"

: build-dir /build/lib
;

alias src_list :
Code
;

lib JamTest
: src_list
: <variant>_debug
;

-----------------------------
and the contents Root/Code/jamfile are:

project _Code
: usage-requirements <include>.
: build-dir /build/obj/Code
;

obj foo : foo.c ;

alias _Code : foo ;

I build using:
bjam toolset=pc debug JamTest

-----------------------------
The problem occurs when, after a successful build, I make a change to foo.h. When I run bjam again, it believes that the project is up to date and foo.c is not recompiled. However, if I rename foo.c to foo.cpp and change the jamfile to reflect this it correctly detects the change in foo.h and recompiles foo.cpp. I am baffled. I've attached pc.jam below, the definitionsthe custom toolset uses if that's any help. I'm also using Boost.Build V2(Milestone 10) and Boost.Jam 03.01.10.

Thanks,
Austin
