	"-b" is a GCC option.  You cannot use bare AIX linker options on
the GCC commandline.  You need to use -Wl,-brtl to pass -brtl to the
linker phase.

gcc under AIX

Trying to build a program with gcc under AIX I get the following errors:

It seems that AIX ld cannot find some libraries.
But those libraries (libACE.so and libgcc.a) exists in the working directory and in 
several directories, all of them listed in the LD_LIBRARY_PATH environment 
variable.
I tried with and without switch -brt.
I also built the same project under linux and solaris succesfully with no change.

Did somebody have the same problem when porting to AIX?
