regex.3.gz belongs to cygwin-doc package

https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fcygwin-doc%2Fcygwin-doc-2.11.1-1&grep=regex.3.gz

regcomp.3p belongs man-pages-posix

https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fman-pages-posix%2Fman-pages-posix-2013-a-1&grep=regcomp.3p

I assume one system has both packages and the other not.

As I have not the second installed, for me

$ man regcomp
No manual entry for regcomp
