well i hope this isn't an FAQ, i skimmed through the lists and didn't
find anything on this topic.
Trying to compile KDE-1.0 with a self built egcs-1.1b on a Linux system
with libc.so.5.4.46 (SusE5.3) failed when sys/wait.h was included.
Tracking down the error a little bit, i found that obvoiusly typeof()
doesn't work inside a struct or union declaration that doesn't have a
tag.
e.g., the following does not compile:
int main(int argc, char *argv[])
{
int y;
union {
typeof (y) a;
int b;
} a;
}
however, if you give the union a tag, it compiles ! try:
int main(int argc, char *argv[])
{
int y;
union u {
/* ^^^ */
typeof (y) a;
int b;
} a;
}
the same problem shows up with struct declarations.
both examples compile with gcc-2.7.2.1, so i doubt this is a bug in
egcs.
If anybody can help me , PLEASE reply by email also, because i'm not
subscribed to the list... thanks
