Subject: Yet one more explicit cast of pointer difference to uint32_t.
X-Git-Tag: 0.15~141
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f5e9045c3ff1083695beb8da19277241bd50f8e2;p=re2c

Yet one more explicit cast of pointer difference to uint32_t.

Much the same as previous commit: array of length bounded with 32 bits,
first pointer points to some random element. second pointer points to
the beginning of array (unless there were some errors in calculatins
that would have likely crashed re2c anyway).

Fixes [-Wconversion] warning.
