Michael, I believe one of the last remaining problems with the compilation of threads in Win32 platforms, maybe others, is that the line-endings on the files are totally incorrect. When I look at the files I see double spaced lines with line-endings of the CR-CR-LF variety. This causes all kinds of problems when the CW preprocessor tries to parse multi-line macros as it only parses the first line and error on the rest, for example: ### mwcc Compiler: # File: ..\src\exceptions.cpp # ------------------------------ # 49: || defined(__CYGWIN__) # Error: ^^ # declaration syntax error Which is the second line of: # if defined(_WIN32) || defined(__WIN32__) || defined(WIN32) \ || defined(__CYGWIN__) It will likely be easier for me to fix this directly than have you try and get the line endings just right, as the editor I use has functionality to fix those problems. Would it be OK for me to fix those at this time? I don't want to collide with anything you might be changing. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq
