Hi Boost-Users,

I understand that boost process has v2 and v1 is deprecated, but I thought v1 will at least work on for existing stuff.
Between 1_87 and 1_88 process v1 stopped working with v1 code. Something changed v1-incompatible with the includes, like:
boost::process::child is unknown.
error: ‘child’ is not a member of ‘boost::process’
   73 |     std::vector<boost::process::child> m_processes;

Is this known or easy-to fix?
