Hmm... I have seen that on Cygwin:
$ objdump.exe -p foo.exe | fgrep ImageBase
returns always:
ImageBase 00400000
I have seen also that there are, in Emacs source tree, other systems
(see src/s/mips.h, for example) which define 'TEXT_START 0x00400000'.
So, not knowing how 'to read or write', I have applied these
self-explanatory patches...

...and Emacs (rev. 100739) bootstraps fine...
But, are those patches the best solution? Are we sure that in the future
there will not pitfalls or drawbacks?
Eli, Ken, have you comments and/or suggestions?
Thanks,
Angelo.
