[gentoo-dev] [PATCH] multilib.eclass: get_exeext for mingw/cygwin exe suffix, #588330

[Michał Górny]

Add a get_exeext function that can be used to obtain executable program
suffix specific to the platform, in line with get_libname and
get_modname. It is necessary to correctly reference built programs on
non-standard platforms where executables use some suffix (like .exe).
