[SOLVED] Empty lines in xdm config files after current update

Many xdm related config files contain empty lines at the beginning after todays current xdm update. For example

--- /etc/X11/xdm/Xstartup	2012-05-22 06:25:58.000000000 +0200
+++ /etc/X11/xdm/Xstartup.new	2013-07-07 08:44:13.000000000 +0200

 #!/bin/sh

Same is seen in Xresources, Xservers, Xreset and xdm-config.

Any one knows what is up here?

I don't know what's up, but patched it with an awk script in the build phase. A real understanding of what's happening would be better, since the upstream source and build script didn't change and this seems to only happen on -current. But this will do for now. Thanks!

After some sleuthing I figured out this undesired behavior under gcc 4.8 is due to gcc's
pre-processor now pre-including stdc-predef.h for the translation unit to make it fully C11-compliant.

This quick patch I put together, while not elegant, solves the problem. I've alerted upstream but
given blank lines should not break anything, I wouldn't count on much effort being invested in this.

Removing leading blank lines post-build has the same effect as applying my patch. However, if you go that route, you
probably want to re-order things a bit in xdm.post-install so you don't get extraneous blanks in the backups (e.g.
/usr/doc/xdm-1.1.11/Xsession.orig).
