error on build from source

Hi,

Postgres will not build on a Slackware-9.1 system.

make[3]: *** [utf8_and_gb18030.o] Error 1
make[3]: Leaving directory `/usr/src/postgresql-7.4.1/src/backend/utils/mb/conversion_procs/utf8_and_gb18030'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/usr/src/postgresql-7.4.1/src/backend/utils/mb/conversion_procs'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/usr/src/postgresql-7.4.1/src'
make: *** [all] Error 2

At this point I am looking suspiciously at gcc, which is...

gcc (GCC) 3.2.3

Have others run into this? Or do I need to look elsewhere to get it to
build?
