Hi, I try hard to compile ghc6.4 under MS Windows XP with really new cygwin. What am I doing wrong, this is the official 6.4 release? Some hints I should know about compiling under MS Win? /cygdrive/g/ghc/ghc-6.2.1/bin/ghc -H16m -O -I. -Rghc-timing -I../../../librarie s -fglasgow-exts -no-recomp -split-objs -c Compat/RawSystem.hs -o Compat/RawS ystem.o -ohi Compat/RawSystem.hi G:/cygwin/home/mai99dnn/tmp/ghc1832.hc: In function `s3SQ_entry': G:/cygwin/home/mai99dnn/tmp/ghc1832.hc:113: too many arguments to function `rawS ystem' <> make[4]: *** [Compat/RawSystem.o] Error 1 make[3]: *** [boot] Error 2 make[2]: *** [boot] Error 1 make[1]: *** [boot] Error 1 make[1]: Leaving directory `/home/mai99dnn/software/ghc-6.4/ghc' make: *** [build] Error 1 Cheers Patrick
