Config error with irix 5.3

[Nik Gervae <ngervae@xxxxxxxxxx>]

Can anyone shed light on how to get zsh to build on irix 5.3? I haven't
a clue how to fix the config script....

tankgirl:~/zsh-> ./configure
loading cache ./config.cache
configuring for zsh 3.0.0
checking host system type... mips-sgi-irix5.3
checking for gcc... gcc
checking whether we are using GNU C... no
checking how to run the C preprocessor... /lib/cpp
checking for working const... no
checking whether cross-compiling... yes
checking for gcc option to accept ANSI C... no
checking for function prototypes... no
checking size of long... configure: error: can not run test program while cross
compiling
tankgirl:~/zsh->

Thanks in advance!
