No; without the semicolon, "V1=x V2=y cmd ..." sets the environment
variables V1 and V2 only during the execution of "cmd ...", and
furthermore will make sure they're exported so "cmd" can see them (in
sh/bash, a variable must be exported to be visible to commands).

I'm not really sure what you mean.

A simple Makefile.am might look like:

    bin_PROGRAMS = foo
    foo_SOURCES = file1.c file2.c hdr1.h

If you add "file3.c", just make sure it's included in foo_SOURCES:

    foo_SOURCES = file1.c file2.c file3.c hdr1.h

That will make sure it gets built and linked into foo, and will take
care of all dependency generation etc.

[Header files mentioned in foo_SOURCES will not have any effect at
build-time, but having them there ensures they're considered part of the
source files, so that "make dist" etc. will do the right thing.]
