	Malloc comes from libptmalloc3.a and not from libc due to some strange 
malloc flavours. I don't understand why gento complaims about 
libptmalloc3 because ptmalloc is used by GNU libc...

	You can use autoreconf or similar tools to rebuild m4 macro files.

	I don't understand this message. All relocatable files don't have any 
executable stack :

cauchy:[~/rpl/build/src] > scanelf -eR .
  TYPE   STK/REL/PTL FILE
ET_REL --- --- --- ./rpl-instructions_p7.conv.o

ET_REL --- --- --- ./librpl_a-sommations.conv.o
...

and final executable has :
ET_EXEC RWX --- RW- ./rpl

	If you find an explanation, please send me a mail. RPL/2 doesn't use 
executable in stack.

	This allocator comes from glibc and has been tested in 64 bits mode on 
several systems and architecture (including sparc64 with alignement). 
This last message is a false alarm because ptmalloc3 is a system level 
library, not a user level one.
