Thx alot!
I know that my path is messy, but having "/" in the path should not be
all too fatal.
Furthermore, I probably did not set any of those strange paths myself
(this is afterall Windows ;) ).
@Eliot: Good idea to set MANPATH!
>MANPATH=/usr/share/man PATH="/usr/bin:/foo" strace man bar |grep
'foo/share'
returns nothing and fixes the issue!
IMHO at least in Windows/Cygwin creating MANPATH from PATH makes no
sense! (although I now get the idea what was the rationell!) Reasonably
setting MANPATH should IMHO be a default...

Greetings, Riedel,Till (TM)!
I traced down my problem with really slow man page views this:
{{{
>>PATH="/usr/bin:/foo" strace man bar |grep 'foo/share'
}}}
I am getting this:
{{{
13 39756 [main] man 6688 normalize_posix_path: src /foo/share/man
16 39772 [main] man 6688 normalize_posix_path: /foo/share/man =
normalize_posix_path (/foo/share/man)
13 39785 [main] man 6688 mount_info::conv_to_win32_path:
conv_to_win32_path (/foo/share/man)
12 39810 [main] man 6688 mount_info::conv_to_win32_path: src_path
/foo/share/man, dst C:\tools\cygwin\foo\share\man, flags 0x3000A, rc 0
16 39912 [main] man 6688 mount_info::conv_to_win32_path:
conv_to_win32_path (/foo/share)
14 39942 [main] man 6688 mount_info::conv_to_win32_path: src_path
/foo/share, dst C:\tools\cygwin\foo\share, flags 0x3000A, rc 0
}}}
If my PATH is the real one this goes on forever, and generates some
problems,like:
You have lots of duplicated, obsolete and overlapping paths in your %PATH%.
I suggest you start from some homecleaning.
Not to mention strange ones, like "/".
{{{
>>time man bar
No manual entry for bar
real 0m23.650s
user 0m0.000s
sys 0m0.108s
hanging e.g. on
20 2449004 [main] man 8124 mount_info::conv_to_win32_path: src_path
//share/man, dst \\share\man, flags 0x4022, rc 0
}}}
VS.
{{{
>>PATH=/usr/bin/ bash -c "time man bar"
No manual entry for bar
real 0m0.082s
user 0m0.031s
sys 0m0.045s
}}}
Any ideas why man does look for "share" in the whole path? Tbh I haven't
looked at the man source code. Thx in advance!
