[Privoxy-devel] PATCH for pcre2 support

[Gagan Sidhu]

thanks for catching this.

this is abug. for some reason when i cross compile, it works fine.

but when i build again on my system, i get the errors you’re talking about.

can you check the actual code changes though and i can worry about the automake stuff later?

i just tried to copy the complicated logic used by the original macros, but for pcre2.

turns out it’s not that simple :/

Thanks,
Gagan
