>From the error message I'ld say you just need to include <errno.h> in
zend_ini_scanner.l (like in zend_language_scanner.l), can you verify
this?

it seems, that since my debian unstable upgraded from flex 2.5.4a-14 to
2.5.4a-15, I can't compile the Zend Engine anymore. It throws an error
in zend_ini_parser.c and if I compare a zend_ini_parser.c genearated
with the -14 version and one from -15 version, there are indeed
differences where the error occurs.
here's the error-mesage from make:
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../main

and here the relevant part from the debian-changelog:
flex (2.5.4a-15) unstable; urgency=low
* if a signal is delivered while the parser is in the read routine
(coded by flex), the result is flex reports and YY_FATAL_ERROR
causing
plan to exit. The race condition appears much more frequently
than
one might expect because plan spends a good deal of time in read
routine while gcc is preparing the input. I cleaned up another
problem
case beyond what is given in the patch. closes:
Bug#125611
I have no idea about this flex stuff, so maybe someone else out there
can fix that :)
