FreeBSD to Solaris cross compile

[Bernie Doehner]

Hi:

I am trying to cross compile to build a FreeBSD->Solaris crosscompiler so
that I can build gcc to run under Solaris natively. Has anyone on this
list done this successfuly?  I am having lots of problems compiling
libgcc (seems to want unistd.h and some other headers) and I am rather
confused. 

Please drop me a line so that I can straighten out my confusion and
document these quirks for the FAQ mods.

Thanks.

Bernie
