	  	The last parameter to gv_stashpv/gv_stashpvn/gv_stashsv is a bitmask
	  	of flags, not a boolean, so correct the documenation and callers.

Fri Jul  3 15:06:40 1998  Jarkko Hietaniemi  <jhi@iki.fi>

	- Integrated IPC::SysV 1.03 to Perl 5.004_69.

Change 142 on 1998/05/31 by <gbarr@pobox.com> (Graham Barr)

	- Changed SHMLBA from a constSUB to an XS sub as on some systems it is not
	  a constant
	- Added a missing MODULE line to SysV.xs so ftok is defined in IPC::SysV

	Applied patch from Jarkko Hietaniemi to add constats for UNICOS

Change 135 on 1998/05/18 by <gbarr@pobox.com> (Graham Barr)

	applied changes from Jarkko Hietaniemi <jhi@iki.fi> to add
	new constants and ftok
	
	fixed to compile with >5.004_50
	
	surrounded newCONSTSUB with #ifndef as perl now defines this itself
