#
# Notes:
#
# * Compilation Defines:
#
# FAKE_STAT
# - Enables time faking also for files' timestamps.
#
# NO_ATFILE
# - Disables support for the fstatat() group of functions
#
# PTHREAD
# - Define this to enable multithreading support.
#
# PTHREAD_SINGLETHREADED_TIME
# - Define this if you want to single-thread time() ... there ARE
# possibile caching side-effects in a multithreaded environment
# without this, but the performance impact may require you to
# try it unsynchronized.
#
# FAKE_INTERNAL_CALLS
# - Also intercept libc internal __functions, e.g. not just time(),
# but also __time(). Enhances compatibility with applications
# that make use of low-level system calls, such as Java Virtual
# Machines.
#
# NO_CACHING
# - Disables the caching of the fake time offset. Only disable caching
# if you change the fake time offset during program runtime very
# frequently. Disabling the cache may negatively influence the
# performance.
#
#
# * Compilation addition: second libMT target added for building the pthread-
# enabled library as a separate library
#
# * Compilation switch change: previous versions compiled using '-nostartfiles'
# This is no longer the case since there is a 'startup' constructor for the library
# which is used to activate the start-at times when specified. This also initializes
# the dynamic disabling of the FAKE_STAT calls.
