I need a pdf support with Qt 4.7.1 in my QNX 6.5.0, installed to VMWare Workstation. I try to build poppler ver.0.20.3 
(poppler.freedesktop.org) in next few steps (GCC 4.4.2.):

0) Configure, build and install all dependencies of poppler (Fontconfig-2.10.1, Cairo-1.12.2, libjpeg-8d and libpng-1.5.
12).

1) Set proper environment variables to build poppler:

#!/bin/sh
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export CFLAGS="-I/usr/local/include/pixman-1 -I/usr/include/qt4 -I/usr/pkg/include"
export LDFLAGS="-L/usr/local/lib -L/x86/usr/lib -L/usr/lib -L/usr/pkg/lib"
export LIBS="-lpixman-1 -lQtGui -lQtCore -lQtNetwork -lopenjpeg"
export CXXFLAGS=${CFLAGS}
export FREETYPE_CFLAGS=-I/usr/local/include/freetype2
export FREETYPE_LIBS="-L/usr/local/lib -lfreetype"
export FONTCONFIG_CFLAGS=-I/usr/local/include/fontconfig
export FONTCONFIG_LIBS="-L/usr/local/lib -lfontconfig"
export CAIRO_CFLAGS=-I/usr/local/include/cairo
export CAIRO_LIBS="-L/usr/local/lib -lcairo"

2) Unpack and configure it (see log file in the attachment):

# ./configure --disable-jpeg

3) When I try to build poppler it fails with error in goo/gfile.cc:

Functions getuid(), getcwd() and getcwd() are in my <pwd.h> file, but their declarations are covered 
by macros:

#ifdef __EXT_POSIX1_198808
	/* declarations */
#endif

Error with stat::stat(char*&, stat*) because g++ trying to call struct constructor instead of call function stat(char*&, stat*), that declared in <sys/stat.h>.

Declaration of mkstemp() in <stdlib.h> is macro protected too:

#if defined(__EXT_XOPEN_EX)
	/* declarations */
#endif

I tried to build poppler in Win7 (msys+MinGW) and everything was ok, it's works. Poppler binaries for pkgsrc from ftp.
netbsd.org are without \Splash\ support, but I need this backend.

Define macros manually in $CFLAGS ("... -D__EXT_XOPEN_EX -D__EXT_POSIX1_198808") did not solve my problem.

So, my questions:

1) What is the correct way to set POSIX version in headers?
2) Why stat() function can't be called?
3) What I need to do to define __EXT_XOPEN_EX macro?

Thanks.
