 sure.
 
 i think, from the feedback i got from david miller and matt green, the
 C compiler builds ok on sunos 4.1.4
 
 it is only the c++ compiler that has a problem (i haven't tried the building the
 ada/java/objc/fortran compilers as i have never used them).
 
 the problem seems to be because gcc3 doesn't ship with (or sunos doesn't have?)
 definitions for a bunch of functions that it thinks it should find, e.g for
 div_t and so on.

 i'll try that.  will it make much of a difference ?

 haven't tried without the cflags.  at this stage i am assuming the problem
 is specifically with function definition issues for c++, which wouldn't
 be influenced by the cflags (but please let me know if i am wrong)
 
 
 when i get a little more time, i am going to try and find all the missing
 functions on another more up to date OS and see if i can reuse them on
 sunos4.
