[Ace-users] [ace-bugs] Warnings in tests with g++4.2

[Johnny Willemsen]

Hi,
 
Thanks for using the PRF form. I have fixed the void* in my local tree, I
have more changes pending and commit this later this week. For the
ARGV_Test, can you try to make the constructors of ACE_ARGV explicit? The
cast seems not a good solution. Just be aware that we haven't build ACE/TAo
with GCC 4.2, you are the first person who tries it ;-). We welcome patches
for supporting GCC 4.2
 
REgards,

	make[1]: *** [.obj/Malloc_Test.o] Error 1
	
	tests/Malloc_Test.cpp
	
	    DOES THE PROBLEM AFFECT:
	        COMPILATION? Yes
	
	    SAMPLE FIX/WORKAROUND: 
	
	tests/ARGV_Test.cpp
	Casting added helps to resolve the constructor's ambuiquty.
	 ACE_ARGV args3((ACE_TCHAR **)argv);
	
	tests/Malloc_Test.cpp
	Make initialization.
	  void *bar = 0;
