MSVC linker does not fail, but this is for uniformity and to make it 
work easily with cccl
when linking against libraries: if I leave the "lib" prefix in octave 
libraries, then
1) "-loctave" should be expanded into "liboctave.lib"
2) Win32 libraries does not have the "lib" prefix such that "-lkernel32" 
should be expanded
into "kernel32.lib"
To solve this problem and because MSVC libraries are usually not 
prefixed with "lib" like
in the UNIX world, I made the library prefix configurable in the 
configure script. Hence my
link commands can contain "-loctave -lkernel32" without any special 
handling.
