[Confuse-devel] conditional building of examples

[Nathan Brink]

I was wondering if building of the files in examples/ could be made 
optional. I'd like to have a ./configure --disable-examples option for 
two reasons:
1. When crosscompiling confuse for mingw32, the examples don't compile 
because SIGUSR*, SIGHUP, etc. aren't defined
2. Sometimes the package is installed using a package manager such as 
Gentoo's Portage. The examples--which are noinst_PROGRAMS that are not 
even used for make check or for building the parts of libconfuse--are 
compiled, never run, and then thrown away after running make install. 
This wastes a small amount of time for the user which, given confuse's 
short compile time, becomes somewhat significant.

I have attached a patch (which hopefully isn't eaten by the ML) that 
adds the --enable-examples option to ./configure. It defaults to 
enabling the compilation of examples so that those who download and 
compile the source can easily play with the examples. It has worked on 
my system to avoid the compilation of the examples--allowing make to 
return a success while crosscompiling to mingw32.

Please respond with any suggestions or thoughts about my 
patch/methodology/reasons.
