But what if you want to call a function returning a static from another
source module?  Say for instance, in main.c you have a function declared:
static char *get_cmd(FILE *fp)
and you want to call it from misc.c.  You can't say
extern static char *get_cmd(FILE *fp)
since most compilers will respond with the "too many storage classes" error.
If I declare it: extern char *get_cmd(FILE *fp) this gives a warning
under GCC.  I'm not sure whether it works with Turbo C.  How should
such a function be declared externally?
