Hi,  
I tried compiling ruby-1.8.5 on AIX5.3 and everytime it fails saying  
“unable to compute size of rlim\_t” during the configure command. I was  
wondering if anybody was able to compile ruby on AIX5.3 and have its  
binaries

The following is a part of config.log

configure:12857: checking for intrinsics.h  
configure:12865: result: no  
configure:12879: checking for rlim\_t  
configure:12924: gcc -c -g -O2 conftest.c \>&5  
configure:12930: $? = 0  
configure:12937: test -z “$ac\_c\_werror\_flag” || test ! -s conftest.err  
configure:12940: $? = 0  
configure:12947: test -s conftest.o  
configure:12950: $? = 0  
configure:12962: result: yes  
configure:12965: checking size of rlim\_t  
configure:13443: gcc -o conftest -g -O2 conftest.c -lm \>&5  
collect2: library libm not found  
configure:13446: $? = 1  
configure: program exited with status 1  
configure: failed program was:
