Hi Witold,

I am still trying to compile svgtex on linux.

Some errors occurred due to difference of compiler’s specification.

Some of the errors seems to be fixed by myself but others are still unsolved.

The unsolved problems are like below.

```
svg_pattern.h: In member function 'svg::rectangle svg::pattern::bounding_box()':
svg_pattern.h:382: error: no matching function for call to 'svg::pattern::to_root(svg::req_prepare)'
svg_element.h:342: note: candidates are: void svg::element::to_root(svg::request&)
```

GCC’s way of handling reference seems to somewhat different from MSVC’s compiler?

Once I tried to fix this problem by way of like this.

```
//to_root(req_prepare(request::prepare_measure, measure));
request req = req_prepare(request::prepare_measure, measure);
to_root(req);
```

By this way, I could make compile and get a svgtex.so file.

That plugin file can use as usual ways, but it becomes not able to use some of the SVG files.

Probably there needs to modify the definithion of to_root() or req_prepare() but I don’t know how to fix this error.

There are about 15 ‘no matching function for call to’ error reported.
