Sorry for my bad english !
Hello and thank you for your excellent work !
I explain my problem: When I try to compile aMule-CVS-20061106(and other cvs versions) under Debian Etch, I do not cease receiving(thousands and thousands) warning messages like this:

./configure --prefix=/usr --with-gtk --enable-unicode --disable-compat24 --enable-optimiseI did not keep the wxgtk configure output but I know that I did not receive any warning or error message and that all the dependences are satisfied.
The configure output for amule:

Configured aMule CVS for 'i686-pc-linux-gnu'.
aMule enabled options:
**** aMule Core ****
Prefix where aMule should be installed? /usr
Should aMule be compiled with i18n support? yes
Should aMule be compiled in debug mode? no
Should aMule be compiled with profiling? no
Should aMule be compiled with optimizations? yes
Should aMule monolithic application be built? yes
Should aMule daemon version be built? yes
Should aMule remote gui be built? (EXPERIMENTAL) yes
Crypto++ library/headers style? embedded
**** aMule TextClient ****

Libraries aMule will use to build:
wxWidgets 2.7.0
crypto++ embedded
libpng 1.2.8
libgd 2.0.33
zlib 1.2.3After some research on the forum, I have to find only these 2 threads without answers or solutions:
http://www.amule.org/amule/search.php?searchid=370419http://www.amule.org/amule/thread.php?postid=57345If you have time, would you have kindness to explain me what causes these thousands of warning messages, and if I can take the risk to continue to compile and use amule in spite of these messages ?
Thanks
