And now, the awful truth will been revealed: guile depends absolutely
on gcc...
Here is the problem: the C preprocessor of Sun, used by
guile-doc-snarf, generates $ $ $ instead of $$$ (as do gcc), and this
for all the triples used by the snarfing mechanism.
This breaks guile-snarf.awk, and hence *.x and *.doc are void.

This is a real and decent bug !
Coming back to the C preprocessor, I do not know if it is the only one
in this case, as the behaviour is ok for the semantics of C.
Perhaps putting the characters between "" will help ?
This will also avoid a compiler choking on $ or @, I am not sure these
2 are legal outsite "".
Other solution is to have cccp in guile...
Sincerely.
