Installing Mesa version 5

[Uli Horn]

Hi

How do I install Mesa version 5?
I have downloaded the library and demo tar.bz2 files?
There is only a cygnus make file and not a cygwin make file - do I use this
one?
When executing 'export LDFLAGS="-lstdc++" ; ./configure --prefix=/usr'
I get the following error:
checking for C compiler default output... configure: error: C compiler
cannot create executables
How can I fix this?
