[csw-users] gcc and autoconf

[Philip Herron]

Just trying to package subversion 1.7.7 think i am going to do a fresh
install again because i realised i was using a 32 bit vm want to be
able to use 64 bit if want. Maybe i didnt install some of the packages
from your repo properly. And it was picking up the sunstudio -mt flag
somewhere like you said.
