Help with hamm needed! Where did GetOpt.h, Regex.h, generic.h etc. , go?

[Igor Bubel <bubel@online-service.de>]

Hello,

I am using Debian to develop and add software modules to a larger program 
for a software company. Recently, I successfully updated my Debian 1.3 to 2.0, 
using autoup.sh and then dselect to get the latest packages. So far, all
works fairly well, until I start compiling the software of the company. It
seems as if I have not installed all header files like GetOpt.h, Regex.h,
generic.h etc. I found in the mailing list archive that popt.h does
replace GetOpt.h if I understood it correctly. But I couldn't find any
information about generic.h and Regex.h. 

My question is: Could someone kindly pinpoint me to documentation or to a
solution for this problem? Why are these header files not included into
Debian anymore?

Thank you very much in advance.
