133 PERL_REVISION (Oldsyms.U):
134 In a Perl version number such as 5.6.2, this is the 5.
135 This value is manually set in patchlevel.h
137 PERL_VERSION (Oldsyms.U):
138 In a Perl version number such as 5.6.2, this is the 6.
139 This value is manually set in patchlevel.h
141 PERL_SUBVERSION (Oldsyms.U):
142 In a Perl version number such as 5.6.2, this is the 2.
143 Values greater than 50 represent potentially unstable
144 development subversions.
145 This value is manually set in patchlevel.h
147 PERL_APIVERSION (Oldsyms.U):
148 This value is manually set in patchlevel.h and is used
149 to set the Configure apiversion variable.
151 CONFIGDOTSH (Oldsyms.U):
152 This is set to 'true' in config.sh so that a shell script
153 sourcing config.sh can tell if it has been sourced already.
155 PERL_CONFIG_SH (Oldsyms.U):
156 This is set to 'true' in config.sh so that a shell script
157 sourcing config.sh can tell if it has been sourced already.
159 PERL_API_REVISION (patchlevel.h):
160 This number describes the earliest compatible PERL_REVISION of
161 Perl ("compatibility" here being defined as sufficient binary/API
162 compatibility to run XS code built with the older version).
163 Normally this does not change across maintenance releases.
164 Please read the comment in patchlevel.h.
166 PERL_API_VERSION (patchlevel.h):
167 This number describes the earliest compatible PERL_VERSION of
168 Perl ("compatibility" here being defined as sufficient binary/API
169 compatibility to run XS code built with the older version).
170 Normally this does not change across maintenance releases.
171 Please read the comment in patchlevel.h.
173 PERL_API_SUBVERSION (patchlevel.h):
174 This number describes the earliest compatible PERL_SUBVERSION of
175 Perl ("compatibility" here being defined as sufficient binary/API
176 compatibility to run XS code built with the older version).
177 Normally this does not change across maintenance releases.
178 Please read the comment in patchlevel.h.
180 PERL_PATCHLEVEL (Oldsyms.U):
181 This symbol reflects the patchlevel, if available. Will usually
182 come from the .patch file, which is available when the perl
183 source tree was fetched with rsync.
185 config_args (Options.U):
186 This variable contains a single string giving the command-line
187 arguments passed to Configure. Spaces within arguments,
188 quotes, and escaped characters are not correctly preserved.
189 To reconstruct the command line, you must assemble the individual
190 command line pieces, given in config_arg[0-9]*.
192 config_arg0 (Options.U):
193 This variable contains the string used to invoke the Configure
194 command, as reported by the shell in the $0 variable.
196 config_argc (Options.U):
197 This variable contains the number of command-line arguments
198 passed to Configure, as reported by the shell in the $# variable.
199 The individual arguments are stored as variables config_arg1,
