Hi Timm. When I merged that commit I didn't realise you had a similar patch
pending. Regarding the printsig patch, I would suggest dropping the 'bool nest
= true' definitions and instead call printsig_nested unconditionally.

Otherwise the patch set looks ok. With it, gcc still compiles systemtap without
error and we are closer to being able to compile systemtap with clang. I still
get an errors when compiling with clang however. ex. `unsupported argument
'auto' to option 'flto='` when compiling
systemtap/python/HelperSDT/_HelperSDT.c
