Subject svn commit: r351841 - /incubator/stdcxx/trunk/src/assert.cpp
Date Fri, 02 Dec 2005 21:41:46 GMT
Author: sebor
Date: Fri Dec  2 13:41:39 2005
New Revision: 351841

URL: http://svn.apache.org/viewcvs?rev=351841&view=rev
Log:

	STDCXX-81
	* assert.cpp: On Solaris 8 and beyond, declared the printstack function
	instead of #including <ucontext.h>, the system header in which it is
	declared, in order to avoid having to #define enabling macros (i.e.,
	__EXTENSIONS__) and deal with the breakage when using a strict compiler
	such as EDG eccp with the long long extension (used in some system other
	headers) disabled.
