Subject: Fixed bug #488: tsticonv fails on Solaris with Sun C compiler.
X-Git-Tag: YAZ.2.1.14~19
X-Git-Url: http://sru.miketaylor.org.uk/cgi-bin?a=commitdiff_plain;h=de11e6bdb853dce80abe2c1223fe490ae0b2ebd0;p=yaz-moved-to-github.git

Fixed bug #488: tsticonv fails on Solaris with Sun C compiler.
We no longer use a negative value in yaz_iconv_trie_dir.ptr member
for a "null" pointer. Instead integer 0 is used and actual ptrs
have an offset +1.
