#   FILE:           ld_so_aix
#   TYPE:           executable, uses makexp_aix
#   SYSTEM:         AIX
#
#   DESCRIPTION:    Creates a shareable .o from a pre-compiled (unshared)
#                   .o file
#
#   USAGE:          ld_so_aix [CC] [arguments]
#
#   ARGUMENTS:      Same as for "ld".  The -bM, -bE, -bI, -H, -T, and -lm
#                   arguments will be supplied by this script.  The compiler
#                   specific ("-lc" or "-lc_r", "-lpthreads", etc) arguments
#                   will be automatically passed to "ld" according to the CC
#                   command provided as a first argument to this script.
#                   Usually, the same CC command was used to produce the
#                   pre-compiled .o file.
#
#   NOTES:          1.  Currently specific to the building of Python
#                       interpreter shared objects, in that the entry
#                       point name is hardcoded based on the object file
#                       name (the "mathmodule.o" file will expect an
#                       entry point of "initmath").  This could be remedied
#                       by the support (or simple expectation) of a "-e"
#                       argument.
#                   2.  The resulting shared object file is left in the
#                       current directory with the extension .so
#                   3.  Uncommenting the "echo" lines gives detailed output
#                       about the commands executed in the script.
