Those backslashes come from eclass/cuda.eclass line 80, which says: ret="${flag}\\\"${gcc_bindir}\\\"" Changing that to ret="${flag}\"${gcc_bindir}\"" removes one layer of backslash quotation and allows me to build =sci-libs/magma-1.4.1. According to the CVS log at https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/cuda.eclass?annotate=1.6 that code has been there since the beginning, but I can't understand how it has ever worked.
