[Scons-dev] compiler (tools) search order in SConstruct

[Ludmil T Zikatanov]

Gary: 
Thanks for the prompt reply.  I am getting from your email that with the current scons version the tool chain specifications are doable but not easy at all. Am I right? 
I hope a new version with this functionality will come out soon.

However, I stumbled when I tried  to write an SConstruct file that searches for "C" and "Fortran" compilers in an order prescribed by me.  For example: assume that  I have "icc", "gcc" and "gcc-mp-4.6" on a mac (all paths to the executables are in the scons path, so no problem finding each of these 3 tools).
