Compiler error

[dsong]

I have trouble to compile the gdb-5.0 under the FreeBSD 4.0. or
FreeBSD 4.1.

The trouble code I have is as following

olib.c: In function `solib_map_sections':
solib.c:369: structure has no member named `som_addr'
solib.c:369: structure has no member named `som_addr'
solib.c:370: structure has no member named `som_addr'
solib.c:370: structure has no member named `som_addr'
solib.c: In function `solib_add_common_symbols':
solib.c:431: storage size of `inferior_rtc_symb' isn't known
solib.c: In function `first_link_map_member':

solib.c:897: invalid use of undefined type `struct _dynamic'
solib.c:901: invalid use of undefined type `struct _dynamic'
solib.c:901: invalid use of undefined type `struct _dynamic'

solib.c:903: invalid use of undefined type `struct
section_dispatch_table'
solib.c:903: invalid use of undefined type `struct

solib.c: In function `current_sos':
solib.c:1099: structure has no member named `som_next'
solib.c:1099: structure has no member named `som_next'
solib.c:1114: structure has no member named

 I can complie and install correctly in the Linux platform.

Can you take a look at this trouble and let me know how can I fix this
error.

Thank you.
