72 You appear to have ELF support. I'll try to use it for dynamic loading.
73 If dynamic loading doesn't work, read hints/linux.sh for further information.

83 You don't have an ELF gcc. I will use dld if possible. If you are
84 using a version of DLD earlier than 3.2.6, or don't have it at all, you
85 should probably upgrade. If you are forced to use 3.2.4, you should
86 uncomment a couple of lines in hints/linux.sh and restart Configure so
87 that shared libraries will be disallowed.

100 ## uncomment the next two lines:
104 # In addition, on some systems there is a problem with perl and NDBM
105 # which causes AnyDBM and NDBM_File to lock up. This is evidenced
106 # in the tests as AnyDBM just freezing. Apparently, this only
107 # happens on a.out systems, so we disable NDBM for all a.out linux
108 # systems. If someone can suggest a more robust test
109 # that would be appreciated.

115 # I tried compiling with DBM support and sure enough things locked up
116 # just as advertised. Checking into it, I found that the lockup was
117 # during the call to dbm_open. Not *in* dbm_open -- but between the call
118 # to and the jump into.
120 # To make a long story short, making sure that the *.a and *.sa pairs of
121 # /usr/lib/lib{m,db,gdbm}.{a,sa}
122 # were perfectly in sync took care of it.
124 # This will generate a harmless Whoa There! message

145 *********************** Warning! *********************
146 It would appear you have a defective bash shell installed. This is likely to
147 give you a failure of op/exec test #5 during the test phase of the build,
148 Upgrading to a recent version (1.14.4 or later) should fix the problem.
