Having selected dash as the default sh makes the configure of DirectFB fail with the following error [SNIP] checking linux/serial.h presence... yes checking for linux/serial.h... yes ./configure: 24583: ./configure: Bad substitution eselect sh list Available POSIX shell implementations: [1] bash [2] dash * Selecting bash back makes it configure and compile properly. Reproducible: Always Steps to Reproduce: 1. Select dash as the default sh provider 2. try to compile dev-libs/DirectFB-1.7.6 Actual Results: DirectFB fails at the configure phase.

ugh, rather than fix their code that incorrectly mixes CFLAGS & CXXFLAGS, they just tried to delete flags from CXXFLAGS that are valid only in CFLAGS: CXXFLAGS="$CXXFLAGS ${CFLAGS//-Werror-implicit-function-declaration/}"
should be all set now in the tree; thanks for the report! Commit message: Drop broken CXXFLAGS munging from configure http://sources.gentoo.org/dev-libs/DirectFB/DirectFB-1.7.6.ebuild?r1=1.1&r2=1.2
