rsync-2.5.1 failed to transfer a 2G+ file (under HPUX 11.11)

[Chuck Fisher]

Compiled rsync 2.5.1 using gcc version 3.0; warnings but no errors after 
defining HAVE_SNPRINTF HAVE_VSNPRINTF, HAVE_C99_VSNPRINTF in lib/snprintf.c
(otherwise make dies while compiling snprintf.c complaining of snprintf being
re-defined).  I had been hoping this version of rsync would allow the transfer 
of large files. 

The attempt to transfer was as follows:

sdx1 25: ./rsync --rsh=/usr/bin/ssh --rsync-path=/usr/local/src/rsync-2.5.1/rsyn
c /scratch/chuck/test2 sdx3:/scratch/chuck
rsync error: received SIGUSR1 or SIGINT (code 20) at rsync.c(229)

I suspect the warnings received during the make are not relevant, but here they
are just in case:
