 4.1 Compile mode
 ================
 
 For "compile" mode, MODE-ARGS is a compiler command to be used in
 creating a `standard' object file.  These arguments should begin with
 the name of the C compiler, and contain the `-c' compiler flag so that
 only an object file is created.
 
    Libtool determines the name of the output file by removing the
 directory component from the source file name, then substituting the
 source code suffix (e.g. `.c' for C source code) with the library
 object suffix, `.lo'.
 
    If shared libraries are being built, any necessary PIC generation
 flags are substituted into the compilation command.  You can pass
 compiler and linker specific flags using `-Wc,FLAG' and `-Xcompiler
 FLAG' or `-Wl,FLAG' and `-Xlinker FLAG', respectively.
 
    If the `-static' option is given, then a `.o' file is built, even if
 libtool was configured with `--disable-static'.
 
    Note that the `-o' option is now fully supported.  It is emulated on
 the platforms that don't support it (by locking and moving the
 objects), so it is really easy to use libtool, just with minor
 modifications to your Makefiles. Typing for example
      libtool gcc -c foo/x.c -o foo/x.lo
    will do what you expect.
 
    Note, however, that, if the compiler does not support `-c' and `-o',
 it is impossible to compile `foo/x.c' without overwriting an existing
 `./x.o'.  Therefore, if you do have a source file `./x.c', make sure
 you introduce dependencies in your `Makefile' to make sure `./x.o' (or
 `./x.lo') is re-created after any sub-directory's `x.lo':
      x.o x.lo: foo/x.lo bar/x.lo
    This will also ensure that make won't try to use a temporarily
 corrupted `x.o' to create a program or library.  It may cause needless
 recompilation on platforms that support `-c' and `-o' together, but
 it's the only way to make it safe for those that don't.
