Bug#812685: mapserver: conflicting types of variable msyystring_icase

[Michael Tautschnig]

Package: mapserver
Version: 7.0.0-8
Usertags: goto-cc
Tags: patch

During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and pbuilder) the build failed with the following error. Please note that we
use our research compiler tool-chain (using tools from the cbmc package), which
permits extended reporting on type inconsistencies at link time.

mapfile.c line 65: error: conflicting types for variable `msyystring_icase'
old definition in module `maplexer' file maplexer.l line 51
signed int
new definition in module `mapfile' file mapfile.c line 65
char

Depending on endianness of the platform, the lexer may use the wrong byte of
msyystring_icase. The attached patch fixes this problem.

Best,
Michael
