Document Classes ⇒ encoding in package chemist.sty & double defined command

[surgeon]

Hi all!
There are to problems I encountered latestly.
First I am using the xymtex package to typeset chemical formulas http://en.wikipedia.org/wiki/Xymtex.
The problem is a part of this package, called chemist.sty:

(/usr/share/texmf/tex/latex/xymtex/chemist.sty
Package `chemist' (ver4.03) <September 02, 2005> [SF]
chemist.sty ver4.03 (for LaTeX2e) 2005/9/2[SF]

LaTeX Font Warning: Encoding `OML' has changed to `T1' for symbol font
(Font) `letters' in the math version `chem' on input line 803.


LaTeX Font Warning: Encoding `OT1' has changed to `T1' for symbol font
(Font) `operators' in the math version `boldchem' on input line 80
3.

Whenever i compile the document these warnings are told. I am using the latex extensions for vim and therefore it is very enervating reading this warnings every time I call the compiler inside of vim, how can I tell latex to keep these warnings for itself?

My second problem is maybe a common one. I am using two packages, where both of them have a command with the same name defined. Then latex too complains about this, but I don't want to know this, it's fine if the one defined by the first package is taken and I am spared these warnings.

How can I tell latex these two things?

Thanks in advance,
Bastian

If you don't care about these warnings, then you can tell VIM-LaTeX to ignore them.

See information about g:Tex_IgnoredWarnings. You can add your own warning text (the first few words of the warning, for example). Just be sure to increase the g:Tex_IgnoreLevel as well.
