Replace getopt_long_only with getopt_long and #include <execinfo.h> is somehow dragged in on BSD systems?

A friend of mine was trying to package this for pkgsrc on their NetBSD machine and two issues cropped up:

• Since getopt_long_only is used instead of getopt_long, they had to edit this out in order to proceed further into the build.
• For some reason, execinfo.h is dragged into the buildpath even though the person's system isn't Windows. I don't know how to modify the file to recognize that what's compiling really is windows. Commenting out the call to print_trace() somehow fixes this, even though execinfo.h was pulled in due to this weirdness.

Their modified glyr / src / glyrc / glyrc.c: http://pastebin.ca/2158525
If it's possible to make BSD specific changes to compiling, that'd be grand. Otherwise I think this would have to be a patch for it to compile under *BSD systems.

Hi there,

Thanks for the hint.
I was not aware that getopt_long_only was a GNU Extension. I'm totally fine with that change.

For execinfo.h: I replaced #ifndef G_OS_WIN32 with #ifdef __linux__ so it only is compiled in for compatible machines I did not found any HAVE_EXECINFO or better-fitting feature macros (sigh)

Give me some feedback if everything compiles fine now.

Friend compiled it with the applied with the applied changes and it works! I also compiled it to make sure the changes didn't do anything weird to building it on Linux boxes.
