Bug ID: 109988
Summary: -iwithprefix doesn't add folder to end of search list
Product: gcc
Version: 11.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ivan.lazaric.gcc at gmail dot com
Target Milestone: ---
```
echo | g++ -iprefix "./" -iwithprefix "." -E -v -
```
Snippet of output:
```
#include <...> search starts here:
./.
/usr/lib/gcc/x86_64-linux-gnu/11/include
/usr/local/include
/usr/include/x86_64-linux-gnu
/usr/include
End of search list.
```
Issue is that "./." is at the front of the list, should be at bottom.
Snippet of `man g++`:
```
-iprefix prefix
Specify prefix as the prefix for subsequent -iwithprefix options.
If the prefix
represents a directory, you should include the final /.
-iwithprefix dir
-iwithprefixbefore dir
Append dir to the prefix specified previously with -iprefix, and add
the
resulting directory to the include search path. -iwithprefixbefore
puts it in
the same place -I would; -iwithprefix puts it where -idirafter
would.
```
^ implying `-iwithprefix` should behave like `-idirafter`
`echo | g++ -idirafter "./." -E -v -`:
```
#include <...> search starts here:
/usr/lib/gcc/x86_64-linux-gnu/11/include
/usr/local/include
/usr/include/x86_64-linux-gnu
/usr/include
./.
End of search list.
```
