[ELPA] Update package: psgml: handle (compile-internal) obsoletion

[Lucien Pullen]

It looks like (compile-internal) has been deleted, finally.  This 
patch
(see attached) adds a check to use the new (compilation-start) 
while
still being compatible with really old versions.

Is it really necessary to keep the legacy call in there?... how 
far back
should we support old versions?  My computer ships with v22, but 
my OS
is from 2013, and the new procedure was already marked as the one 
to use
by that point.

Unrelated... ...

 I'm not very familiar with Emacs' dynamic loader.  Does it 
 optimize
 out the branch instruction on load since it's a comparison of a
 constant? or does compiled code get interpreted literally?  It's 
 only
 a quick branch and calling the external procedure takes much 
 longer,
 but I used the version check instead of (fboundp) since it's 
 probably
 faster than the obarray lookup if the check is performed every 
 time
 you call the procedure.  Old assembly habits die hard.

Anyways, on to the patch file.

Subject: [PATCH] * psgml.el (sgml-validate): use (compilation-start) for
 recent emacs

The procedure (compile-internal) has been deprecated since Emacs v22 and
is removed in at least v24.4.
