This is necessary to keep alignment between the client view of rig->state and the shared libarary view
Including PTHREAD functions in rig->state necessitated this as HAVE_PTHREAD only defined during hamlib compilation.
Clients including hamlib/rig.h did not pick up all the HAVE* config variable that control what gets included

Fixed using the following command:
codespell --write-changes --summary --skip=*.m4 --ignore-words-list="develope,get's,quitt,setts,som,ue,vektor"
codespell --write-changes --summary --skip=aclocal.m4,lib --ignore-words-list="develope,get's,quitt,setts,som,ue,vektor"
