* If we are passed "-" in argv and the user didn't specify '-' in optstring,millert2002-12-081-6/+10
| | | | return -1 like POSIX requires.
* BSD getopt() supports '-' in the optstring so we should too.millert2002-12-081-8/+15
| | | | This is used by a few programs such as man and su.

* 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.
* In srandomdev(), if we can't access /dev/arandom, use the sysctl() instead.millert2002-12-061-10/+27
| | | | | We don't want to use the sysctl() by default since we are reading more than just a few bytes of entropy when setting up the state.
* 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.
