Comeau C/C++ 4.3.0.1 for NetBSD/Intel!!

Comeau C/C++^TM 4.3.0.1 Front-End
Additional information for NetBSD/Intel customers

When using Comeau C++ under NetBSD 1.5+, you may come across the issues discussed below.

You may find you want to use the new --long_long command line option. Note this option can be enabled even in strict mode.
Some NetBSD's /usr/include/sys/cdefs.h have the __END_DECLS macro defined incorrectly for strict mode. You will need to change it from:
```
#define __END_DECLS   };
```
to:
```
#define __END_DECLS   }
```
You can do this by actually changing the real include file, or by making a "shadow" version of it in the include directory of your Comeau C++ installation.
When you first install Comeau C++ on NetBSD, don't inform como4301.setup about libcomo, instead tell it you don't have a standard library. Go build libcomo and only then go back and re-run como4301.setup telling it about libcomo.

If, in C++ mode, you get linker errors such as:

c2.o: In function `main':
c2.o(.text+0x14): undefined reference to `cout'
c2.o(.text+0x19): undefined reference to `ostream::operator<<(char const *)'
c2.o(.text+0x32): undefined reference to `cout'
c2.o(.text+0x37): undefined reference to `ostream::operator<<(char const *)'
c2.o(.text+0x42): undefined reference to `ostream::operator<<(int)'
c2.o(.text+0x55): undefined reference to `endl(ostream &)'
c2.o(.text+0x6e): undefined reference to `cout'
c2.o(.text+0x73): undefined reference to `ostream::operator<<(char const *)'
c2.o(.text+0x7e): undefined reference to `ostream::operator<<(int)'
c2.o(.text+0x91): undefined reference to `endl(ostream &)'
collect2: ld returned 1 exit status

then it is possible that you have not built libcomo properly and/or have not told Comeau C++ to use libcomo after you built it (the source file may have compiled because it picked up the g++ iostreams headers). To resolve this, ensure you've built libcomo properly and also that you've run como4301.setup properly.

Along the same lines as the previous bullet, getting an error such as:
```
"/usr/include/g++-3/stl_vector.h", line 110: error: identifier "_M_start" is
          undefined
      _M_start = _M_allocate(__n);
      ^
```
should be clear indication that you are picking up the wrong standard library (note the /usr/include/g++-3 in the error message). As above, to resolve this, ensure you've built libcomo properly and also that you've run como4301.setup properly.
