A recent commit made it possible to execute such binaries reliably, but that does require them to be installed. As an alternative solution: if a binary with a standard Unix path prefix can't be found but is available as a built-in applet, run the applet. Add the function unix_path() to detect paths starting with /bin, /usr/bin, /sbin or /usr/sbin. Use this function in: - the 'which' applet - shellexec(), describe_command() and find_command() in ash - mingw_spawn_1() See GitHub issue #195. 2020-08-13T13:58:01+00:00 Ron Yorston rmy@pobox.com 2020-08-13T13:13:32+00:00 urn:sha1:16e5930a65f3c7c570b8a0dda8daa19ab4792fa2 Use the new need_system_drive() function in httpd.

To avoid ambiguity that commit considered certain such paths to be relative to %SYSTEMDRIVE%. Extend this to paths representing executables. Add the functions need_system_drive() and auto_add_system_drive() to detect the need for a system drive prefix and to add it if necessary. Use these functions in: - the 'which' applet - the find_executable() function - tab-completion code - PATH look-up, shellexec(), describe_command() and find_command() in ash - parse_interpreter() and mingw_spawn_1() With these changes executable paths starting with a slash are handled consistently, whatever the current drive. 2020-08-13T13:58:01+00:00 Ron Yorston rmy@pobox.com 2020-08-13T10:43:26+00:00 urn:sha1:7d639339e0c46311f8873d560e6f168e71473cd9 Allocate static storage for the system drive string instead of making a new allocation on every call.

Also, since is_absolute_path() is now only used in shell/ash.c move its definition there from include/mingw.h.
