While Compiling Xview I get the following error

gcc -c  -O2 -m486 -DNO_ASM -fpcc-struct-return -I../../.././build/include
-I/usr/local/include  -DSCO -DBROKEN_FTOL -DNO_PROTOTYPE -D_SVID -DSYSV
-DSYSV386 -DOZ_CHANGE   -DOS_HAS_LOCALE   frame_init.c
frame_init.c: In function `frame_default_done_func':
frame_init.c:58: `NULL' undeclared (first use this function)
frame_init.c:58: (Each undeclared identifier is reported only once
frame_init.c:58: for each function it appears in.)
frame_init.c: In function `frame_init':
frame_init.c:104: `NULL' undeclared (first use this function)
frame_init.c: In function `frame_create_footer':
frame_init.c:377: `NULL' undeclared (first use this function)

It seems that the error is because of lack of recursive expansion of macros.
I did not find in the gcc manual a flag that can be set to enable recursive
expansion of macros.

I use gcc 2.3.3 on SCO UNIX 3.2.2 (SYSV R3)
