[I am resending this message with a new subject because nobody seems to be reading the old thread.] I wanted to test the fix for ticket #711 but I am stuck because there is no current snapshot of ghc 6.5 for mingw. (The last one is dated end of February, the patch was commited on March, 2nd.) I saw that the patch is scheduled for milestone 6.4.2 but has been commited only for 6.5. When will it be available for 6.4.2? I started learning to compile ghc and I have succeeded with the current head of the 6.4 branch on Debian Linux/testing. Next step is to compile the head on this system. My current problem is a missing symbol when linking stage1/ghc-6.5, namely u_gencat referenced by stage1/parser/Lexer.o. Am I missing some library? (I think my sources are up to date, I pulled only half an hour ago.) Michael
