Hmmm.  IIRC stdint.h is the C99 integer types header file.  The fact it's
missing on your solaris box and the fact that everything works ok on linux
makes me wonder if maybe the version of gcc on your Solaris is much older
than the one on your linux box and that's why it's not working.  Check the
version # on the solaris; if it's really old, get a more up-to-date one at
sunfreeware.com and see if that helps.

Whether or not that will work depends on the build script you're using.  The
instructions that came with it should have been clear about how you're
supposed to set up the directory tree.
