# devised a test for avoiding HP/UX malloc and using GNU malloc instead.

# test for CLISP Common LISP and extended it to cover broken mallocs
# from SGI.  I (<pinard@iro.umontreal.ca>) reworked it a little so it is
# independent of config.guess, and overridable by the installer.

# On IRIX 5.2, libc malloc is broken, but the -lmalloc one was usable.
# So in my packages, I once unconditionally used -lmalloc if it existed.
# This does not do anymore, because the -lmalloc malloc is broken on
# Solaris 2.4 to 2.5.1 (alignment is 4 bytes instead of 8 bytes, as
# reported by John Wells <john@bitsmart.com>).

# Bruno also notes: "HP-UX has two different malloc() implementations.
# Both are broken.  When used with CLISP, the one in the default libc.a
# leads to a SIGSEGV, the one in libmalloc.a leads to a SIGBUS."

# If the installer does not give a preference, we use the included GNU
# malloc if we have the slightest doubt that malloc could be broken,
# this includes cross compilation, and *all* HP/UX or IRIX systems.
# It is crude indeed, but I just do not have enough information for truly
# benchmarking malloc in all cases, but want safe packages nevertheless.
