Hi all, I think removing the -Werror can generate bad code... better to use -fno-strict-aliasing for now. This has the disadvantage of generating slower code in some cases -- I haven't checked this in Pd's case -- but is at least correct.
I think using unions is the correct way to go. This means rewriting PD_BADFLOAT somehow, and I haven't decided the best way to do it...

The hack I used is to look in the makefile in the directory containing the file whose compilation resulted in the warning message and remove all occurrences of -Werror from it. The proper thing to do is to eliminate the warning, in this case I think the use of a union is the way to go, but then you'll find there is another warning that shows up later on about echoed exp or something that looks like a redeclaration of a global in local scope (?)
