> If you run gcc with '--save-temps' flag, and then look into > 'yourfile.s' file, you'll see that uninitialized data is tagged as > "common" (using '.comm' directive) and is put to bss only by linker > when final executable is created. To turn this feature off, use > '-fno-common' flag when compiling your object file. This works, however only if the variables are non-static. If a variable is static the .comm directive is still used. > Not sure if it's all that needed to link gcc-produced object files > with watcom linker, though. For instance, for function 'func ()' gcc > uses _func as symbol name in object files while watcom uses 'func_'. The only problem is that some functions call external functions like _log10. Is the cygwin1.dll source code of that function available? I did a quick search in CVS but couldn't find it. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
