Timo Teräs <timo.teras at iki dot fi> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |timo.teras at iki dot fi --- Comment #21 from Timo Teräs <timo.teras at iki dot fi> --- This caused a regression for non-multilib builds. Now my non-multilib lp64 build fails with: a-cfinve.ads:245:04: warning: in instantiation at a-coboho.adb:55 a-cfinve.ads:245:04: warning: types for unchecked conversion have different sizes Probably because the logic added in this patch to Makefile.in picks up 64-bit file only when multilib is enabled.
