Stuart,
The LIB utility can combine library as well
as OBJ files.
Extracting the OBJ files isn't as convenient, since
the LIB utility doesn't support extraction using wild-
cards. You must specify each OBJ file separately.
This involves first getting the files using the /list option.
In your case, you can combine all the extra lib files
with your obj or lib files by doing the following:
lib /out:liball.lib a.lib b.lib c.lib myobj1.obj myobj2.obj
In this example, "liball.lib" is the output file and will
contain all of the object files from the libraries and
any object files specified on the command line.
