-D : define symbol to have some value:
-D symbol symbol gets the value 'define'
-D symbol=value symbol gets the value 'value'
+ common used examples (see INSTALL for more info):
+ -Duse64bitint use 64bit integers
+ -Duse64bitall use 64bit integers and pointers
+ -Dusethreads use thread support
+ -Dinc_version_list=none do not include older perl trees in @INC
+ -DEBUGGING=none DEBUGGING options
+ -Dcc=gcc choose your compiler
+ -Dprefix=/opt/perl5 choose your destination
-E : stop at the end of questions, after having produced config.sh.
-K : do not use unless you know what you are doing.
-O : let -D and -U override definitions from loaded configuration file.
-U : undefine symbol:
-U symbol symbol gets the value 'undef'
-U symbol= symbol gets completely empty
+ e.g.: -Uversiononly
-A : manipulate symbol after the platform specific hints have been applied:
-A symbol=value append " "value to symbol
-A append:symbol=value append value to symbol
-A prepend:symbol=value prepend value to symbol
-A undef:symbol define symbol to be 'undef'
-A undef:symbol= define symbol to be ''
+ e.g.: -A prepend:libswanted='cl pthread '
-V : print version number and exit (with a zero status).
