It turns out I may not have been looking closely enough. bryner pointed out to me that this warning shows up for gcc as well. My memory of trying it on my RH 7.0 system (which I don't have access to now) was the reverse, but maybe I didn't test what I thought I did. This was fixed by
2000-09-04 Craig Newell <CraigN>
* gcc.c: Undefine "__WCHAR_TYPE__" before redefining it.
in CVS gcc, gcc-c++-2.96-70 will include this fix.

Using the -fshort-wchar option with g++ (but not gcc) gives the following warning for every file compiled: <command line>: warning: "__WCHAR_TYPE__" redefined Steps to reproduce: * create a file called test.cpp containing "int main() { return 0; }" * `g++ -fshort-wchar -o test test.cpp` This seems like the -fshort-wchar option is being tranlated to a -D option at 2 different points (perhaps g++ and gcc), which leads to 2 -D__WCHAR_TYPE__ options, or something like that. It would be nice to see this fixed, since we're using this for Mozilla when the option is available. I haven't tested this on the gcc trunk.
