Subject: tar: remove lint discovered by Sun C compiler
X-Git-Url: https://git.dogcows.com/gitweb?p=chaz%2Ftar;a=commitdiff_plain;h=bad4b0006c872e09129cc1128ab24157af38b0cd

tar: remove lint discovered by Sun C compiler

* src/common.h (WARN_ALL): Don't mask with 0xffffffff; on a 32-bit
host, 0xffffffff is of type 'unsigned int', which makes WARN_ALL
an unsigned int value that is too large to fit into an int, and
the C standard says that this has undefined behavior.  The mask is
not needed, so omit it.
