$NetBSD: patch-rts_StgCRun.c,v 1.2 2015/02/05 00:59:10 pho Exp $
We have to make the visiblity of StgRun and StgReturn to "hidden" not
to trigger a bug in old binutils which results in:
ld: rts/dist/build/RtsStartup.dyn_o: relocation R_X86_64_PC32
against `StgRun' can not be used when making a shared object;
recompile with -fPIC
With this workaround we can no longer override those two symbols using
LD_PRELOAD, but I think there is no reason to do so anyway.
This has already been fixed in the upstream:
