bug#15795: 24.3.50; Compile uses relative filenames, breaks goto next er

Subject: bug#15795: 24.3.50; Compile uses relative filenames, breaks goto next error.

Hello.

I usually compile Emacs in a separate object directory.  From the source 
directory
/Users/jhd/src/emacs/current I use something like:

M-x compile <RET> cd /Users/jhd/src/emacs/obj-cur-osx && make <RET>
A warning/error in *compilation* uses relative filenames:

../../current/src/nsfont.m:889:28: warning: 'ATSFontFindFromPostScriptName' is
      deprecated: first deprecated in OS X 10.8 - Use CTFontCreateWithName()
      [-Wdeprecated-declarations]
      ATSFontRef atsFont = ATSFontFindFromPostScriptName

Clicking on the warning/error, or using next-error, prompts me to find the 
file, it isn't found  automatically.

If I switch to an emacs-24 branch configured exactly the same (same machine, 
same tools, same program versions, same Emacs used for compilation), it results 
in compilation output like this:

/Users/jhd/src/emacs/emacs-24/src/nsfont.m:1230:35: warning: 'Fix2X' is
      deprecated: first deprecated in OS X 10.8 [-Wdeprecated-declarations]
    fliptf.c =  font->synthItal ? Fix2X (kATSItalicQDSkew) : 0.0;

i.e. absolute filenames used and next-error finds the file.

So something in the trunk has changed to use relative filenames.  Either that 
change should be reverted as this is a regression, or compilation-mode should 
be made smarter.

I see this on GNU/Linux also.
