Dear List, We are currently developing with gcc-2.95.2 under a Cygwin environment and are encountering preprocessing problems with macros that span multiple lines with the backslash character. We know that this is a problem with the version of gcc (After reading a previous post on the gnu-gcc-bug list ( http://gcc.gnu.org/ml/gcc-bugs/2000-03/msg00223.html )) but are tied down to this version & development environment and cannot reasonably change any time soon. Are there any known work-arounds available that will facilitate the compilation of code written under Linux to compile correctly under our Cygwin environment? Thanks in advance, Peter Blair.
