Re: [Sablevm-user] Cygwin Compile Problems

[Etienne G. <gag...@uq...>]

In fact, Melanie Lord got SableVM to work under Cygwin.

Her "raw" work is in he sandbox: 

svn ls svn://svn.sablevm.org/developers/mlord/sandbox

I have incorporated, latelym the most important part of it into the
staging branch (i.e. not using lt_dlopen(NULL) for internal VM calls),
but there were some additional minor changes required to get sablevm
and sablevm-classpath to work on cygwin.

The thing is, all is left to do is to integrate these changes
"cleanly" in sablevm[-classpath], so that we don't break the build on
other platforms.
