Mailing List Archive: "initializer does not fit or is out of range" warnings with Sun C compiler

The Sun C compiler gives the following warning when compiling
src/hmac256.c:

cc -DHAVE_CONFIG_H -I. -I.. -DSTANDALONE -mr -Qn -xstrconst -xO2 -xtarget=ultra2 -xarch=v8plusa -c -o hmac256-hmac256.o `test -f 'hmac256.c' || echo './'`hmac256.c
"hmac256.c", line 535: warning: initializer does not fit or is out of range: 220
"hmac256.c", line 535: warning: initializer does not fit or is out of range: 193
"hmac256.c", line 535: warning: initializer does not fit or is out of range: 191
"hmac256.c", line 536: warning: initializer does not fit or is out of range: 149

"hmac256.c", line 537: warning: initializer does not fit or is out of range: 131
...

Should we change:
const char expect[32]
to:
const unsigned char expect[32]

I guess that char is signed and initializing with a value > 127 leads to
this error. I changed the type to an unsigned char array in 1.4.4.

Thanks,
