# Build the mirbsdksh on GNU and other operating systems.
# Notes for building on various operating systems:
# - on most OSes, you will need a pre-installed bash or ksh to build
#   because the Bourne shell chokes on some statements below.
# - Solaris: SHELL=ksh LDFLAGS=-ldl WEIRD_OS=1 ksh ./Build.sh
# - Interix: SHELL=ksh ksh ./Build.sh (also on GNU and most *BSD)
# - Mac OSX: SHELL=bash WEIRD_OS=1 bash ./Build.sh
