Subject: [PATCH] Use unsigned char to squash compiler warnings
Date: Mon, 2 Mar 2015 19:22:31 +0000 [thread overview]
Message-ID: <1425324151-5480-1-git-send-email-bdwalton@gmail.com> (raw)
Sun Studio on Solaris issues warnings about improper initialization
values being used when defining tolower_trans_tbl in
ctype.c. tolower_trans_tbl is defined as char[], which studio's
compiler defaults to signed char[] due to the Solaris ABI. To resolve
this, instead of supplying -xchar or another option at build time,
declare tolower_trans_tbl as unsigned char. Update all appropriate
references to the new type.
