[Sunhelp] Solaris header files

[saul]

I have an Ultra-1 170, 64mb ram, with NO internal Floppy or CD-rom drive.

My problem is this.  When I bought the computer, the seller put a fresh MINIMAL 
install of Solaris-7 on the machine...which means that the "/usr/include" 
directory is virtually empty of all the header files required by MANY c 
programs.  (At least to compile them).

I have access to a solaris 2.6 copy of a full install "/usr/include" directory, 
but the machine is sun4m architecture (a sparc5), and beyond that, the libraries 
may have some subtle differences from the solaris-7 versions.

Does anyone know if it will be OK if I just straight out copy the files from one 
machine to the other, or (even better) of a place that has a public copy of the 
/usr/include directory for sol-7, that I could copy?

Thanks again!
