Does not build on Ubuntu Linux 10.04LTS

[stepelu]

I cannot manage to build it on Ubuntu 10.04LTS via Luarock (but I suspect it is not a Luarock issue).

It this version of libcurl unsupported?

Oldest version with I test is 7.22 (which one installed on Travis)
According Symbols In Versions CURLGSSAPI_ exists since 7.22.
So may be it sufficient just wrap this options to ifdefs based on version or flags (lcflags.h)

#ifdef CURLGSSAPI_DELEGATION_NONE
FLG_ENTRY(GSSAPI_DELEGATION_NONE          )
FLG_ENTRY(GSSAPI_DELEGATION_POLICY_FLAG   )
FLG_ENTRY(GSSAPI_DELEGATION_FLAG          )
#endif

I can not test it. So I would appreciate if you can confirm that it works (or better make PR)

Yes I confirm this fixes the issue, the module compile just fine with this change (I messed up the PR on my side, I would appreciate if you could commit the change instead).

Thank you

On a side note, is there a plan to release a new minor version soon (with this fix) ?
