Postgres failed to compile on debian x86

[Josh Fremer <jfremer(at)earthlink(dot)net>]

This is a fresh Debian stable install.  I think there's a very good  
chance I'm missing some required library, since I've had to install  
everything up to this point by hand.  Any suggestions are hugely  
appreciated.

The config.log is 600k so I'm not going to post the whole thing.   
There are heaps of errors in it, including lots of "syntax error  
before 'size_t'" and "WARNING: xxx.h: present but cannot be  
compiled".  The error that configure quite on is "checking types of  
arguments for accept()... configure: error: could not determine  
argument types.

Here are some bits that may be relevant.  If anyone can tell me which  
parts of this massive log would be more helpful, I'll be happy to  
post them.  Thanks in advance:

  $ ./configure --with-perl --with-openssl --with-includes=/usr/ 
include/linux/:/usr/include --with-libraries=/usr/lib/
