This is committed in r421074. (Do you have any clue what those P and
p's were for?)
At the time I put together the patches I wasn't able to figure that
out. I've now traced it back to aclocal.m4 rev 59473 [1], and it
appears to be derived from the autoconf macro
AC_CHECK_SIZEOF/AC_SIZEOF_TYPE [2] -- P and p are still given special
meaning in the latest autoconf.
m4sugar/m4sh.m4:
as_tr_cpp="sed y%*$as_cr_letters%P$as_cr_LETTERS%;s%[[^_$as_cr_alnum]]%_%g"
If I am understanding this correctly, it is used to better
differentiate "char" from "char *".
