   Notes on compiling NIHCL 3.0 with Sun C++ R2.0 under SunOS 4.0.3
			   October 5, 1990


Problems with stdarg on SPARC
-----------------------------

NIHCL 3.0 contains a hack to make stdarg work with AT&T C++ R2.0 on
the SPARC architecture.  This hack must be removed when compiling with
Sun C++ R2.0 as follows:

errfac/errors.c

#ifndef SUNCC
#ifdef sparc
// Use magic name to make stdarg work
#define sev __builtin_va_alist
#endif
#endif

lib/Class.c

#ifndef SUNCC
#ifdef sparc
// Use magic name to make stdarg work
#define arg0 __builtin_va_alist
#endif
#endif

lib/Exception.c

#ifndef SUNCC
#ifdef sparc
// Use magic name to make stdarg work
#define sev_ __builtin_va_alist
#endif
#endif

ex/Vehicle.c

#ifndef SUNCC
#ifdef sparc
// Use magic name to make stdarg work
#define fname __builtin_va_alist
#endif
#endif

Then recompile these four files with -DSUNCC.


Selection of _main.c for Sun C++ R2.0
-------------------------------------

The "munch" version of lib/_main.c must be used for Sun C++ R2.0
because the "patch" version cannot initialize the static objects in a
shared library, such as libC.so.  Select MAIN = _main.c_m in the top
level Makefile and apply the following patch to lib/Makefile:

always:
	-rm -f targetlist *.o _main.c
	touch targetlist
	ln ${LNFLAGS} ${MAIN} _main.c
	${MAKE} generic
