I tried the source code in attach compiled with:
gcc -mconsole -Wall -DDEBUG_THROW exc.c  exception.c -o exc
(I use mingw/msys, gcc 3.2.3)

if E_test is dfined to be 0 I obtain:

exc.c(30)-f: exception 'E_test' (id 0) thrown
unknow 1

I correctly throw 0, but I catch 1.

if I define E_test 1, 2 and so on it works well (wath I throw is what I
catch)

why this strage behaviour?

thanks

ps: I also tried under linux, gcc 2.96 with the same results
