Subject: math/mpint.h (MP_TOINT): Convert MP digits to target type before shifting.
X-Git-Tag: 2.3.0~39
X-Git-Url: https://git.distorted.org.uk/~mdw/catacomb/commitdiff_plain/c973f431a370a3adbcb3c94f76dc6896a7279235

math/mpint.h (MP_TOINT): Convert MP digits to target type before shifting.

Otherwise conversions to types wider than `mpw' never actually works.
