#39 Return type declarations of function mhash_get_hash_name differ in signedness
Debian package version: 0.9.9.9-5
During a rebuild of all packages in a clean sid chroot (and cowbuilder+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.

error: conflicting function declarations "mhash_get_hash_name"
old definition in module mhash_save_restore_test file ../include/mutils/mhash.h line 58
char * (int)
new definition in module mhash file mhash.c line 244
unsigned char * (int type)
Makefile:589: recipe for target 'rest_test' failed
It seems the header file should be adjusted to match the actual definition in order to help the compiler generate appropriate diagnostics.
Best,
Michael
