Ugly. You could just use fputs instead.
But if you know that the passed in strings are safe aka no format specifiers in them you can leave the code as is as the compiler warning is bogus.
exit(1); }

Well, gcc will optimize fprintf(X,"%s",Y) to fputs(X,Y) (and some other funny stuff when errorMemory is known and constant).
But I disagree with leaving it in as-is ... It is sloppy coding and might lead to later problems when used cut&pasted.

You mean to fputs(Y,X) ? That's my gripe with fputs that it has a different order of arguments than fprintf.

Sure, the compiler will do a lot of stuff but what it cannot do is improve readability of the code. If one means "write the string out unmodified" then fputs is a better choice as it makes the intention immediately visible.

Well the error strings are really just static const strings declared at the top of the file. So the code is *correct* and the gcc warning is *bogus*.
It is sloppy coding and might lead to later problems when used cut&pasted.
I don't feel strongly about this. But if it gets replaced it should use a construct that better expresses the intent.

If you've got a better patch, please submit. I opened a bug and put these patches there, as they aren't correct. I was only trying to get Wine compiling without errors again, a proper fix would be appreciated.
