At the moment it appears that 'gcc','zlib','fastjar', and 'libiberty' can
be configured in any order relative to each other (nice and straightforward).
If anyone knows of specific configure order dependencies, they should tell
me.  I'll be spending a while fiddling with gcc and src trying to identify
any other real configure order dependencies.

Nathanael,

Some heads up.

GDB requires an ISO C compiler and on some systems that involves running the compiler with specific flags (-Ae, I think, on HP/UX?). The problem is that GDB can't test/configure this directly. By time time it has a say in the matter, it is too late. The top level will need to do this very early on.

While GDB has a depencency on the SIM directory, it resolves it by testing for ${srcdir)/../sim so that should be ok.

While INSIGHT has a dependency on tcl/tk, it appears to resolve it doing some pretty agressive hunting. It looks in both ${srcdir} and `pwd`.

Andrew
