gcc 3.4.1 (gcc 3.3.3 also) allows statements before declarations:
{
int i1;
printf("bla");
int i2;
}
even if I use -ansi (and -Wall -Wshadow -Werror-implicit-function-declaration
-Wstrict-prototypes -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings)
I got no warning
gcc 2.95.3 and other c compilers
fail to compile that code

We are always interested in improving the quality of the manual. Could you let us know how the manual might be improved so that you would have noticed the "Mixed Declarations" section documenting this extension, and the documentation of -Wdeclaration-after-statement, before making this bug report? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17096 ^ permalink raw reply [flat|nested] 4+ messages in thread
