I've got CLN and GiNaC headers installed in ~/target/x86_64-linux-gnu/include,
so '#include <ginac/ginac.h>' happened to work (which is a bad thing).

It was complete, but a bit incorrect (specifically, I've messed up #include
directives).

I think the patch was correctly applied. Just in a case, I've built GiNaC
from from the `official' branch (before sending the previous mail). Still,
`make check' shows no errors (or something unusual) at all.

I doubt it.

The information I'm asking for is:
1. Architecture and OS,
2. Compiler version,
3. CLN version,
4. Compiler flags,
5. Any unusual configuration options.

$ git branch -a
* master
origin/GiNaC-international
origin/HEAD
origin/experimental_fclasses
origin/ginac_1-0
origin/ginac_1-1
origin/ginac_1-2
origin/ginac_1-3
origin/ginac_1-4
origin/master
$ git remote -v show
origin git://www.ginac.de/ginac.git
$ git diff origin/master | wc -l
0
That is, there's no difference.
Best regards,
Alexei
