Re: ncurses-native compile error -- i'm starting to blame gcc-5.0.0 [SOLVED]

  never mind ... i was just pointed at this fedora-specific page:

https://lists.fedoraproject.org/pipermail/devel/2015-February/207549.html

which discusses the impact of trying a mass rebuild on fedora
packages using gcc-5.0.0, wherein it's explained that a number of
packages now fail to build because:

cclive-0.9.3-4.fc22.src.rpm
cvc4-1.3-7.fc22.src.rpm
dans-gdal-scripts-0.23-5.fc22.src.rpm
emacs-24.4-3.fc22.src.rpm
ember-0.7.2-3.fc22.src.rpm
flamerobin-0.9.3-8.20130401snap.fc22.src.rpm
ghc-gtk-0.12.5.0-3.fc22.src.rpm
ghc-webkit-0.12.5.1-3.fc22.src.rpm
gnote-3.14.0-1.fc22.src.rpm
ksh-20120801-21.fc22.src.rpm
libason-0.1.2-2.fc22.src.rpm
libcmis-0.5.0-1.fc22.src.rpm
libgpg-error-1.16-1.fc22.src.rpm
libixion-0.7.0-3.fc22.src.rpm
liborcus-0.7.0-5.fc22.src.rpm
ncurses-5.9-17.20140906.fc22.src.rpm
openldap-2.4.40-5.fc22.src.rpm
perl-5.20.1-315.fc22.src.rpm
xorg-x11-server-1.16.2.901-1.fc22.src.rpm
xorg-x11-server-utils-7.7-10.fc22.src.rpm
zsh-5.0.7-4.fc22.src.rpm
	these packages failed to build because of the changes in the preprocessor;
	gcc started to generate line directives to better detect whether a macro
	tokens come from a system header - see http://gcc.gnu.org/PR60723
	The fix is to use the -P option if the code isn't prepared to deal with
	such directives.


  so i just added to my local.conf:

CPPFLAGS_append_pn-ncurses-native = " -P"

and that appears to have solved this build problem. i'm guessing i'll
still hit a few more build errors because of gcc-5.0.0.
