Either fix the code so it complies with the C90 standard (as hmjd's answer suggests), or tell gcc to use a newer version of the standard.

C does permit mixed declarations and statements starting with the C99 standard.

If you use

gcc -std=c99 -pedantic

or

gcc -std=c11 -pedantic

it should work.

Move declaration of originalAttrs to the top of the scope in which it is used. The error is unrelated to use of ConsoleInfo.wAttributes but to the location of the declaration of originalAttrs. Without seeing the entire code, it is probably something like:

printf("hello\n"); /* For example. */
int originalAttrs = ConsoleInfo.wAttributes;

To fix:

int originalAttrs;
printf("hello\n"); /* For example. */
originalAttrs = ConsoleInfo.wAttributes;
