bug#18552: Possible bug building emacs trunk with Fedora 19-x86_64

Dmitry,

I also built (or tried to build) the trunk on my out of the box Fedora 20 
x86_64 system... It failed the same way. I tried this because I thought I might 
have messed up with the FC 19 system.

I also ran your test after building libjpeg version 9. Your sample code did see 
the new header file but didn't produce any output either.

Regards,

George...

1) Always update to latest official package from your distribution.  For Fedora 
19, it
    seems to be libjpeg-turbo-1.3.1-2 and libjpeg-turbo-devel-1.3.1-2, 
respectively.

2) Make sure that you don't have alien installation of libjpeg in non-standard
    location, or make sure that this installation is not accessible by Emacs'
    configure script.

3) Run this:

    echo -e "#include <jpeglib.h>\nversion=JPEG_LIB_VERSION" | cpp | grep -E 
"version= *(6[2-9]|[7-9][0-9])"

    If you don't see any output, re-check 2) because Fedora 19 definitely ships
    the jpeg library recent enough to built Emacs trunk.
