The header is from a prebuilt binary (from OpenCSW).  That is built 
with gcc and not the Sun compiler.  And curlbuild.h says

/* Allow 32 and 64 bit headers to coexist */
#if defined __amd64 || defined __x86_64 || defined __sparcv9
#include "curlbuild-64.h"
#else
#include "curlbuild-32.h"
#endif

which AFAIK are gcc and not Sun defines.  You could try adding 
-D__sparcv9 to the CPPFLAGS, or compile RCurl with OpenCSW's gcc 
build (but 64-bit gcc is another can of worms).

I've pointed out to Jun Zhang several times that 64-bit Sparc Solaris 
is really pushing it, and 32-bit R on Sparc Solaris has been much more 
successful.  Given that x86_64 boxes (Solaris or Linux) are so much 
faster at computation than Sparc ones, I don't see the point of 
building 64-bit Sparc Solaris R -- if 32-bit R is not enough you need 
a faster machine.
