| | | | | | | | | flag from its optional argument if permutation is disabled. The idea was that since "r:" would match "-r foo" then "r::" should match "-r foo" too as long as we know that things have not been reshuffled. Unfortunately, this causes incompatibilities with GNU getopt_long when the POSIXLY_CORRECT environment variable is set. OK deraadt@

* Traditionally, getopt(3) has treated "--foo" the same as "--". However,millert2004-02-041-10/+9
| | | | | | | | this can cause confusion when a user tries to use a long option with a program that only supports short options. Furthermore, it appears to be in violation of POSIX, which states that "--" shall indicate the end of argument processing, not any string that begins with "--". OK otto@ and closes PR 3666.
* If permutation is disabled (as it is via getopt(3) or when POSIXLY_CORRECTmillert2003-09-221-2/+9

* BSD getopt() supports '-' in the optstring so we should too.millert2002-12-081-8/+15

* For getopt_long_only() we *do* want to match single-character optionsmillert2002-12-071-41/+36
| | | | | as shortcuts for long ones, but only if this would not conflict with a short option in optstring. Now binutils gas works.
* Fix two compatibility issues with our getopt_long_only() vs. the GNU version:millert2002-12-061-28/+61
| | | | | | | | | | | | | | o Check for long options even when not at the beginning of an option. For instance, if -a is a short option w/o an arg and -static is a boolean long option then -astatic is valid for getopt_long_only(). o If a potential long argument does not match longopts and the first character is not a short option, print a warning and skip the rest of the argument. Also clean up some trailing whitespace and change return value of parse_long_options() from -2 to -1 when unmatched and in long_only mode. With these fixes the binutils ld seems happy with our getopt_long_only()
* Correctly handle -Wlong_arg (no space between -W and long_arg) when "W;"millert2002-12-051-6/+8

* Reorganize this so that getopt_only_only() works correctly.millert2002-12-051-221/+208
| | | | | | | | In order for getopt_only_only() to work we need to check for long options before short ones. I have merged getopt_internal and getopt_long_internal into a single function with the actual long args parsing broken out into a separate function. This also simplifies the flow of control.

getopt_long_only(). At some point this should replace the BSD getopt(3) but we are not there yet. While I am here add protection from the multiple getopt() definitions due to conflicting standards.
