Re: [sigc] Build fails on Arch Linux

About the build directory: I don't know if 'build' is the best possible name for that directory. Other packages, e.g. glibmm and gtkmm, also have build directories with m4 files. I don't think it's meant for out-of-tree-builds.

About the compilation errors: The results of some configure checks are strange.

checking if C++ compiler supports the use of a particular specialization when calling operator() template methods.... no
checking if C++ compiler supports the use of a particular specialization when calling operator() template methods omitting the template keyword.... no
checking if C++ compiler allows usage of member function in initialization of static member field.... yes
checking whether C++ library symbols are declared in namespace std... no
checking for non-standard Sun libCstd reverse_iterator... no

The first two 'no' here results in SIGC_WORKAROUND_OPERATOR_PARENTHESES being defined as sun_forte_workaround, which is probably wrong.
The 'no' in the fourth line, testing whether C++ library symbols are declared in namespace std, is not reasonable. That's an obsolete test, which has long been unnecessary. Even half-modern C++ standard libraries have their symbols declared in namespace std. Something is wrong here, but I don't know exactly what's wrong. Reasonable results are 'yes' on at least one of the first two tests, and on the fourth test.

About the email being sent late: I am subscribed but it seems it had to be accepted by the moderator because it was a bit big because of the terminal output I pasted.

About the m4 files: I started the build in an empty build directory because that's what I did with emscripten too (only there I had a different directory and here I just emptied build). It seems this really was the problem because when copying the two .m4 files from the build directory of the tarball the native build works. But shouldn't m4 macros be in a seperate directory that is used no matter which directory you use for an out-of-tree-build / if you don't do an out-of-tree-build at all?

Also, when I copy those two files to the emscripten build directory and rerun configure, that works. But make still fails after that. Here is the output, this time not in the mail itself... http://pastie.org/private/sanrhzyff9u6dxpfinpwg
