[Mingw-users] io.h in system include directory overridden by local one

[Martin K. <mk...@ya...>]

I am trying to build indent-2.2.9 under mingw and msys. This is my first ever build package build.

Mingw is installed in c:\mingw and Msys is in c:\msys\1.0.

I ran "configure --prefix=/mingw" then make

make fails on the first file, backup.c with this message

  source='backup.c' object='backup.o' libtool=no \
          depfile='.deps/backup.Po' tmpdepfile='.deps/backup.TPo' \
          depmode=gcc3 /bin/sh ../config/depcomp \
          gcc -DHAVE_CONFIG_H -DLOCALEDIR=\"/mingw/share/locale\" -I. -I. -I.. -I. -I. -I../intl  -g -O2 -c `test -f 'backup.c' || echo './'`backup.c
  In file included from backup.c:89:
  c:/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/dirent.h:38: error: field `dd_dta' has incomplete type
  c:/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/dirent.h:85: error: field `dd_dta' has incomplete type
  make[3]: *** [backup.o] Error 1

I have traced the problem to the fact that this package contains a file called io.h and is
referenced from backup.c as 
  #include "io.h"

On the other hand, dirent.h references the system include file io.h as
  #include <io.h>

I think that the compiler is supposed to differentiate between these two files based on 
configuration of the include file paths. Is this right? 

If so I cannot determine how to set the include path so that files bracketed with <>
are included before other directories.

Any guidance is appreciated.

Best regards,
Marty
