Bug description

Full_Name: Jun Furuse
Version: 3.07
OS: msvc
Submission from: lamarck.inria.fr (128.93.1.21)

Hi,

I found a difficulty of compilation with msvc, in the case that
a responsefile is required: i.e. the case the command line goes longer
than 256 chars. At this moment, for example,
the option -cclib "/link /libpath:blahblah" is stored
wrongly inside responsefile in two lines as follows:

"/link"
"/libpath:blahblah"

and the /libpath option is ignored by the compiler:

Command line warning D4002 : ignoring unknown option '/libpath:blahblah'

The option /link /libpath:blahblah must be stored in one line like:

"/link /libpath:blahblah"

For a quick workaround, I use -cclib "/link/libpath:blahblah"
at this moment...

This one will be hard to fix. The argument to -cclib is split into words so as
to support the popular idiom -cclib "-lfoo -lbar", used e.g. for labltk
configuration. Should fix once Makefiles have been cleaned up.

This issue has been open for way too long, and doesn't seem to affect anyone but the reporter, who found an excellent workaround. Suspending this PR.
