Sigbjorn's last optimization (checking for -mno-cygwin only for mingw32 targets) kicked out -O from the default SRC_CC_OPTS. Apart from a minor performance hit for some parts of GHC, it yields a GHCi which can't load HSbase_cbits.o because `lstat' is unknown, at least on SuSE 7.3. A little investigation showed the rather arcane reason: lstat and friends are inline functions and therefore not in libc.so, only in its static counterpart. Normally this is not a problem at all, but the CPP INLINE trickery in fptools/libraries/base/cbits/PrelIOUtils.c manages to get a reference to lstat into PrelIOUtils.o if -O is not given. %-} A similar problem exists for fstat, too. Simple solution: Re-add -O to SRC_CC_OPTS, simplifying configure.in a bit on the way.
