Summary: VA_COPY() brokenness
Product: rsync
Version: 2.6.6
Platform: Other
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: skunk@iskunk.org
QAContact: rsync-qa@samba.org
Building rsync on a Solaris 10 / AMD64 system:

cc: acomp failed for lib/snprintf.c
*** Error code 2
make: Fatal error: Command failed for target `lib/snprintf.o'
----(end snip)----
The system is using the fallback definition of VA_COPY(), i.e. "(dest) =
(src)", instead of the va_copy() function. Neither HAVE_VA_COPY nor
HAVE___VA_COPY is defined. Why not? Because they are defined as macros in the
system headers, and rsync's configure script looks for them via
AC_CHECK_FUNCS.
