I get the program to compile and link correctly. It will run. However, sometimes it will print a "$" in place of a numeric digit in the output file when specific valid input files are selected. We originally discovered this problem with a version of the program compiled under the B20.1 environment. The problem still exists under the Cygwin V1.0 environment. Upgrading the version of gcc to 95.2 didn't help either. A version of the program compiled under the standard default cygwin environment does NOT exhibit this behavior. Neither does a Unix version compiled with gcc on a Sun Ultra 10. So, the problem appears to be some type of obscure bug in the DLL library handling the fprintf() statements when compiling/linking with the -no-cygwin option specified. At this point, it appears that I have three options to create a standalone, single file executable that can be run on any Windows PC without providing a separate copy of the Cygwin1.dll: 1. Somehow determine the source of the actual bug causing my problem. This appears unlikely, unless someone out there on the list knows how I should proceed to find it and possibly fix it. 2. Determine the correct commandline incantations for the gcc compile/link steps to include the necessary Cygwin1.dll functionality required into the application executable. So far, I have not been successful doing so. Any pointers on how to correctly do this would be appreciated as this would be the quickest and easiest solution for me. 3. Configure "cook", a make-like program I use to control builds of my applications, to use a different, eg. commercial, PC compiler/linker. This is doable, but it requires a lot of additional conditional code to handle the differences between "PC-style" builds and "Unix-style" builds, making the "cookbook" files harder to maintain for use on different platforms. So, I would appreciate any suggestions on how to accomplish option 2 above successfully. Of course, any comments regarding option 1 are welcome as well.
