# sets  e. g. to LINUX, OS_MAJOR_VERSION to 2 and OS_MINOR_VERSION to 6
# by calling the 'guess_env' shell script, where the actual probing happens
# Also sets PLATFORM_COMPILE_FLAGS to be included when compiling C/C++ code
#
# requires:
# - TOPDIR

# provides:
# - PLATFORM
# - OS_MAJOR_VERSION and OS_MINOR_VERSION
# - GCC_MAJOR_VERSION and GCC_MINOR_VERSION
# - PLATFORM_COMPILE_FLAGS
# - EXE
# - SO
# - INSTALL
