This is not standard C and it is not standard for a reason - the feature
opens a can of worms, it is pretty hard to support it without introducing
regressions and/or limitations.

See f.i. the recent descussion on the pcc list, it is long but here are
a couple of messages which make good points:

 https://marc.info/?l=pcc-list&m=142195333911806&w=2

 https://marc.info/?l=pcc-list&m=142201611028645&w=2

IOW, C is probably not the right language for this feature.

I would say tcc is neither the right compiler to add features to :)
if we want it to be small and fast. Especially the intrusive features
like the nested functions should be kept out, IMVHO.
