[PATCH] make x86 math-emu in 2.4.21 compile with gcc 3.3

[PATCH] make x86 math-emu in 2.4.21 compile with gcc 3.3

[Erik Andersen]

I'm surprised this hasn't shown up before, but I guess nobody has
tried compiling 2.4.21 for i386 using gcc 3.3 yet.  Currently the
x86 math-emu code does not compile with gcc 3.3 due to some
missing semicolons and quotes.  This patch fixes things up so it
compiles once again.
