When I compile hpijs-1.4.1, I had to change some as follows:

1) add the function as suggested by Peter Bosch from bell-labs

to the file which contains main() function,

// Ugly, G++ for Plan 9 needs to be installed correctly.
void
ctors(void)
{
	typedef void (*func_ptr)(void);
	extern func_ptr ___CTOR_LIST__[];

	for (int i = 0; i != (int)___CTOR_LIST__[0]; i++)
		___CTOR_LIST__[i + 1]();
}

and and in the top of the main function call the function:

	ctors();

2) in my case I had to add two functions to vsnprintf() and snprintf() to libc library.
 then, I copied snprintf.c and vsnprintf.c files from /sys/src/ape/lib/ap/stdio to
/sys/src/gnu/ape/libc/stdio.   You may also want to add two lines for those two
functions into /sys/include/gnu/stdio.h like:

extern int snprintf(char *, size_t, const char *, ...);
extern int vsnprintf(char *, size_t, const char *, va_list);

Of course you have to change /sys/src/gnu/ape/libc/stdio/mkfile, too.

3) then, recompile /386/lib/gnu/libc.a.   Don't forget to ranlib to it.
You may want to add some neccessary files which I forgot.   I remember
it was neccessary to recompile the library.
