           Summary: mingw32 fails to build gnatlib due to missing sys/wait.h
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P2
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dhazeghi at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: i?86-*-mingw32

Building a cross-compiler to i386-pc-mingw32 fails when build gnatlib:

make -C gcc gnatlib_and_tools
...
make[2]: Entering directory `/home/dara/branch/objdir/gcc/ada/rts'
../../xgcc -B../../ -c -DCROSS_COMPILE -DIN_GCC   `echo -g -O2  -fexceptions 
-DIN_RTS |sed -e 's/-pedantic//g' -e 's/-Wtraditional//g'`

/include -I./../.. adaint.c
adaint.c:68:22: sys/wait.h: No such file or directory

This is true: mingw32 has no sys/wait.h. But configure should either work around 
this, or not allow gnatlib to be built on mingw32.
