To: gcc-bugs
When compiling code with -Wshadow, gcc whines if external struct or
so is first declared (like 'extern struct foo bar;') globally and
then locally.
Environment:
System: Linux haapana 2.4.22 #12 SMP Fri Nov 7 04:07:28 EET 2003 i686 unknown unknown GNU/Linux
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: mcore-unknown-elf
configured with: /work/gcc/configure --target=mcore-elf --with-gnu-as --with-gcc --disable-nls --enable-languages=c,objc,c++ --with-gnu-ld --prefix=/emb/cross-gcc-current --program-prefix=mcore-elf- --program-suffix= -v --with-newlib --with-headers=/pub/devel/gnu/newlib-1.11.0/newlib/libc/include
How-To-Repeat:
/* ***** start of test.c ***** */
/* Compile: 'mcore-elf-gcc -Wshadow -c test.c -o test.o' */
extern struct foo bar;
void dummy()
{
extern struct foo bar;
}
/* ***** end of test.c ***** */

Fix:
Don't use -Wshadow.
