>Description:
I tried to write a spec file that used the %c option, but it is no longer accepted by the driver.  The error is printed by line 5234 of gcc.c.

The gcc.info documentation says that %c is accepted, however:
> `%c'
>     Process the `signed_char' spec.  This is intended to be used to
>     tell cpp whether a char is signed.  It typically has the
>     definition:
>          %{funsigned-char:-D__CHAR_UNSIGNED__}

This is probably a documentation bug, rather than a code bug.

The documentation on the spec files seems quite out-of-date.
For example, I cannot figure out, from the documentation, what does this entry mean in the spec file.
 %{fsigned-char&unsigned-char}
