From: Doug Kehn Date: Wed, 27 May 2015 23:51:53 +0000 (-0500) Subject: package/ncurses: Fix GCC 5.x preprocessor failure X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4297e7298edbef6dde75d8bf468441c6a242da5c;p=buildroot.git package/ncurses: Fix GCC 5.x preprocessor failure Building ncurses 5.9 with GCC 5.x fails with a syntax error, caused by earlier preprocessing. This failure is more likely when building for host (e.g. host-ncurses) that recently updated to GCC 5.x.
