yes, this is the right place.

this depends on the GM installation. I have to check whether
there are differences for 1.6 or 1.5

no, there shouldn't be an impact.

I will test more on Solaris. One thing which is not really
motivating is that the compiler dies when applying the
same techniques as for Linux. Also example code will work
when using gcc in 32 bit mode, with -m64 I will get
a connection refused, a SEGV under CC

Some of these issues might be an installation issue
at our site and help will be appreciated [since you
are from SUN ;-]

For example, can I somehow create a library (using CC) which
I can use for linking to remap functions ?

I will post here, when enhancements for Solaris are available
for download.

regards,
Markus
