compiling gnu-gs-5.50 error in gp_unifs .. don't know

[Mike Wünscher]

Hi all,

I tried to compile gnu-gs-5.50 on a Suse Linux 6.4 with standard installed
environment ( kernel 2.2.14,  includes, libs ).

I used the unchanged unix-gcc.mak as the Makefile and run make. I got this
error below. I'm not a C-programmer, so I can't find the reason for this.
Please give me a hint.

gcc `cat
./obj/cc.tr`  -O2 -Wall -Wcast-align -Wstrict-prototypes -Wwrite-strings -fn
o-common  -I. -I./obj  -o ./obj/gp_unifs.o -c ./gp_unifs.c
./gp_unifs.c: In function `gp_enumerate_files_next':
./gp_unifs.c:268: storage size of `stbuf' isn't known
./gp_unifs.c:335: warning: implicit declaration of function `stat'
./gp_unifs.c:336: `S_IFDIR' undeclared (first use in this function)
./gp_unifs.c:336: (Each undeclared identifier is reported only once
./gp_unifs.c:336: for each function it appears in.)
./gp_unifs.c:268: warning: unused variable `stbuf'
make: *** [obj/gp_unifs.o] Error 1

Thanks for help

Mike
