Configuring a custom scara kinematics module.

I modified scarakins a couple years ago and it was working well for me.  A while back, after an upgrade (I'm not sure which version) halcompile started failing.  I don't use this machine much so ignored it assuming it was a bug someone would eventually address. It doesn't seem to be the case.  In fact the scarakins.c module that ships in the 2.9.2 still fails with error.
Compiling realtime scarakins.c
Linking scarakins.so
/usr/bin/ld:scarakins.ver:2: syntax error in VERSION script
collect2: error: ld returned 1 exit status
make: *** [/usr/share/linuxcnc/Makefile.modinc:123: scarakins.so] Error 1

There are a few forum posts about it but the answer usually seems to be, "Don't do that.  Instead use userkins.comp as a template"

Ok,  Now I'm trying to port my forward/inverse functions to the userkins template.   I'm a terrible C programmer and I'm stuck.  It doesn't seem to be a problem with the functions themselves, just getting variables initialized.   Could someone help me fix my code?  I've attached the current gypsykins.comp module.

I suspect that this might fix it:

stackoverflow.com/questions/35530964/com...or-in-version-script

(I think it is due to grep inserting colour codes in the output, and then the script not being able to parse the result)
