c++.stlsoft - Missing Shim?

Hi,

  This code (with both options) works fine on MSVC6:

<code>
stlsoft::cmdargs::option res;
winstl::path& sequencePath

if (cmd.has_option("seqPath", -1, res))
{
   sequencePath = res.value;            // option1
   sequencePath = res.value.c_str();  // option2
   // ...
</code>

Using CodeBlocks (http://www.codeblocks.org/) with mingw gcc does not like
option1 and only accepts option2.
Seems like it's missing a c_str_ptr() shim, no?

These are the errors I get:

Unfortunately, GCC does not properly detect functions used in templates 
unless they are *declared* before the template.

Alas, the only other workaround (apart from specifying a C-style string, as 
you have done) is to ensure that the shim for the shim'd type is included 
before the type that will be using it. In your case, you'd need to make sure 
that the include for path is included before cmdargs.
