>Environment:
System: OSF1 baobab.cs.uwplatt.edu V4.0 1530 alpha
Machine: alpha
	
host: alpha-dec-osf4.0g
build: alpha-dec-osf4.0g
target: alpha-dec-osf4.0g
configured with: ../gcc-3.2/configure --with-stabs --enable-languages=c,c++,f77,java
>Description:
On the alpha, it seems HAVE_SYS_STAT_H is not being set properly.  When I
build ("make bootstrap" followed by "make install"), I get the following
error: 

        /usr2/sys/usr/local/src/b/gcc/xgcc -B/usr2/sys/usr/local/src/b/gcc/ -B/usr/local/alpha-dec-osf4.0g/bin/ -B/usr/local/alpha-dec-osf4.0g/lib/ -isystem /usr/local/alpha-dec-osf4.0g/include -c -DHAVE_CONFIG_H -g -I. -I../../../gcc-3.2/libiberty/../include  -W -Wall -Wtraditional -pedantic ../../../gcc-3.2/libiberty/getpwd.c

        *** Exit 1

        Stop.
I then edited getpwd.c to change the line
        #if HAVE_SYS_STAT_H
to
        #if 1
and getpwd.c builds just fine.

>How-To-Repeat:
"make bootstrap" (which requires a number of fixes for Digial Unix; see
earlier PR'S) followed by "make install".
>Fix:
See description.
