I suspect that your runtime/libc is defining fgetc as a macro which breaks any code that uses it as an identifier. Ideally, your runtime should be fixed to use a proper function, but you could probably work around it with something like

static char * fix_fgets(char *s, int n, FILE *stream) { return fgets(s, n, stream); }
#undef fgets
static char * fgets(char *s, int n, FILE *stream) { return fix_fgets(s, n, stream); }
