Unfortunately your attempt to override the default CFLAGS fails, in http://koji.fedoraproject.org/koji/getfile?taskID=1024704&name=build.log you can see the following fragment:

+ CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
 -mtune=generic -I/usr/kerberos/include'
+ DEBUG=

The real fix is to use:
    make %{?_smp_mflags} CFLAGS="%{optflags}" DEBUG=""
Only that in this case the build fails due to something looking like a small programming error (see the attached log).The presence or absence of /usr/include/kerberos made no difference in my local build and I do not have right now the time to dig further.

I also suggest to contact the author and ask for a clarification of the license. Strictly speaking, everywhere in the source files he speaks about what we call "GPL+", only the reference on his website is GPLv2.

Created attachment 327960 [details]
log of build failure when using Fedora's CFLAGS

Created attachment 327964 [details]
new spec, fixes all issues that I am aware of

Created attachment 327965 [details]
disables the usage of the bundled strndup and teaches Makefile to use install

with the new spec and the attached patch, everything seems fine. let me know if you are comfortable with the modifications that I suggest and I will do a full review

BTW we already have http_ping [0] in Fedora which seems very similar - I don't think that's a problem but I thought I'd mention it in case someone wants to compare features.  And http_ping's maintainership is up for grabs in any case if someone wants it...

Manuel, thanks for the patch and the reworked spec file.

Here are the new files:
