### This file is just a very small wrapper needed to run the real make/Init.gmk.
### It also performs some sanity checks on make.

# /usr/bin/make lacks basically every other flow control mechanism.

# The .FEATURES variable is likely to be unique for GNU Make.

  $(error Cannot continue)

# In Cygwin, the MAKE variable gets prepended with the current directory if the
# make executable is called using a Windows mixed path (c:/cygwin/bin/make.exe).
