FYI, my team uses GNU Make to perform the actual builds. Make automatically
detects changed source files by comparing the timestamps of the source
files to the timestamps of the built files. Make is not limited to building
executable files, it can be configured to build, for example, documentation
or even websites. Make can run any tool that can be run from a .BAT script.

If you really need a text file with a list of changed files, rules like the
following will do that:

sources := $(wildcard *.cpp)
changemarks := $(sources:.cpp=.changed)

.SUFFIXES: .changed

changes.txt: $(changemarks)
    del $@
    rename changelist $@

    echo $< >>changelist
    touch $@

Windows executables for GNU Make (and other GNU tools) are available at
