Expand regex on multiple lines in Vim

regular expressionvim

I am working on removing comments from a C source file. Let's focus on multiline comments
/* … */ and ignore the inline ones (//)

The following command seems to work with (solaris) sed:

s:/\*.*\*/::g

However in Vim (7.2) it only works if the whole comment is on one line. How can I make it so the .* spreads over multiple lines? I tried doing the follwing 

s:/\*.*[\r]*.*\*/::g

but it didn't work …

I believe you'd want

s:/\*\_.*\*/::g

\_ tells it to include newlines in the following character set (well, ., anyway).
