I was so surprised I did a bit of Googling.  The easy solution to the
problem is to compile your code in 64-bit mode, as this limitation only
applies to the 32-bit ABI (from fopen man page):

USAGE
A process is allowed to have at least {FOPEN_MAX} stdio
streams open at a time. For 32-bit applications, however,
the underlying ABIs formerly required that no file descrip-
tor used to access the file underlying a stdio stream have a
value greater than 255. To maintain binary compatibility
with earlier Solaris releases, this limit still constrains
32-bit applications.
