[vim/vim] Vim HEAD (e40d75f) doesn't build with --enable-perlinterp=dynamic with perl 5.22.2 or 5.24.0 (#810)

[Rob Hoelz]

To reproduce:

$ perlbrew install -Duseshrplib 5.22.2 # I use perlbrew to install perls; you don't need to use it if you don't want to
$ perlbrew use perl-5.22.2
$ perl -v 

This is perl 5, version 22, subversion 2 (v5.22.2) built for x86_64-linux

...
$ git clone https://github.com/vim/vim
$ cd vim/
$ ./configure --enable-perlinterp=dynamic
$ make

Build output:

Starting make in the src directory.
If there are problems, cd to the src directory and run make there
cd src && make first

When digging into this, I noticed some trickery in if_perl.xs that dealt with inline macros; it appears that PERL_NO_INLINE_FUNCTIONS is defined before perl.h is included, and then inline.h, which relies on some of the macros defined in perl.h if PERL_NO_INLINE_FUNCTIONS is not defined, is included later.

Basically this is already discussed in #790. Not that obvious as that issue was initially based on some wrong assumptions and the title hasn't bee adjusted yet.
In particular see #790 (comment).

[Rob Hoelz]

Ah, sorry for the duplicate! I did a cursory search for perl on the issues, but at first glance that one didn't seem related.

[Rob Hoelz]

Closed #810.
