Bug#982310: libglib2.0-dev: Depends directly on libpcre3-dev (old) and indirectly on libpcre2-dev (new)

[Diederik de Haas]

Package: libglib2.0-dev
Version: 2.66.6-1
Severity: normal

I just did an "apt-get build-dep linux" and noticed that both old
(pcre3) as new (pcre2) PCRE libs got installed.
Quering aptitude as to why, pointed both towards libglib2.0-dev.
That seems silly/weird to me, hence this bug report.

$ aptitude why libpcre2-16-0
i   libglib2.0-dev  Depends libselinux1-dev          
i A libselinux1-dev Depends libpcre2-dev             
i A libpcre2-dev    Depends libpcre2-16-0 (= 10.36-2)
$ aptitude why libpcre16-3
i   libglib2.0-dev Depends libpcre3-dev (>= 1:8.31) 
i A libpcre3-dev   Depends libpcre16-3 (= 2:8.39-13)
