Thanks for all the replies, here and elsewhere. Since by now, further 
ones are arriving very slowly only, I'd like to give a quick summary.

I'll quote just one reply in full, since in just a few lines it 
illustrates the main points:

"In my case the customer requested SDCC based project but it failed to
compile into the small flash size. Debugging was quite difficult. Using
the Simplicity Studio and Keil Compiler pairing made the code small
enough to fit into the device and made debugging much easier."

The 3 most-cited reasons to not use SDCC were:

* Lack of efficiency of the code generated by SDCC.
* Better debug support and integration in non-free toolchains.
* Availability of paid support for non-free compilers.

In my opinion, the best way forward from here to make SDCC more 
competitive vs. non-free compilers is:

0) Improve machine-independent optimizations
1) Improve machine-dependent optimizations for mcs51
2) Improve debug support and integration
3) Find and fix bugs

I'd estimate the total effort at a full-time position for slightly more 
than a year, though even less effort should allow some improvements.
