Unfortunatelly, I can't.
If I don't do this, aap detects VC++. As I'm writing this tool for
Cygwin, and as it uses some functions specific to Cygwin, I can't use
VC++.

That's much better. Thanks!

However, that's not perfect yet.

With a build from scratch, that's fine: g++ is correctly called during
the link phase.
However, if I only need to (re)link (because I forget a library in the
first place, or I decide to use another library), aap calls gcc and not
g++.

I guess we should keep in mind (/on the disk) the object files have been
produced with g++ and not gcc.

Anyway, as it is quite rare we only need to just link, this is not
critical.

BTW, I notice that the error message says I have a problem into
test_realpath.cpp and not tests/test_realpath.cpp. However, I do not
know if it is an issue that'd better be fixed with aap, or if it must
must done in a compiler-plugin, that should try to detect in which
directory the file is.

Actually, I was thinking to correctly detect some AAP error messages as
error messages.
For instance, I have defined compiler/aap.vim with:
    ....
    " %+A is used to accept "Do not know" in the error message
    set efm+=%+EAap:\ Do\ not\ know\ %m
    " GCC link errors (undefined reference to..)
    set efm+=%[%^)]%#):%f:%m
    ....
but I was wondering if a more complete solution already exist.


Thanks.
