Use upstream sources for libgssapi
Fix libgssapi_krb5, libgssapi_ntlm, and libgssapi_spnego (help needed)
I have difficulty with creating gssapi_asn1.h with asn_compile. I have figured out that Makefiles in kerberos5/lib/libgssapi_[krb5|ntlm|spnego] and lib/libgssapi/Makefile` need to be change, but I could not make it since I'm not very skilled in Makefiles. Any advice would be greatly appreciated.
