I can’t build a profiled HEAD compiler.

In validate.mk I put

GhcProfiled = YES

GhcStage1HcOpts = -DDEBUG

GhcStage2HcOpts = -fprof-auto

GhcLibHcOpts += -Wwarn

GhcLibWays += p

But then ‘sh validate –fast’ gives

rts/RtsFlags.c: In function ‘read_heap_profiling_flag’:

rts/RtsFlags.c:1562:26: error:

     error: assignment discards ‘const’ qualifier from pointer target type [-Werror]

rts/RtsFlags.c:1565:27: error:

     error: assignment discards ‘const’ qualifier from pointer target type [-Werror]

cc1: all warnings being treated as errors

`gcc' failed in phase `C Compiler'. (Exit code: 1)

Does anyone have ideas for how to fix this?
