# The library can be built with some alternative behaviour to
# facilitate development of applications on Win32 that will be ported
# to other POSIX systems. Nothing definable here will make the library
# non-compliant, but applications that make assumptions that POSIX
# does not garrantee may fail or misbehave under some settings.
#
# PTW32_THREAD_ID_REUSE_INCREMENT
# Purpose:
# POSIX says that applications should assume that thread IDs can be
# recycled. However, Solaris and some other systems use a [very large]
# sequence number as the thread ID, which provides virtual uniqueness.
# pthreads-win32 provides pseudo-unique IDs when the default increment
# (1) is used, but pthread_t is not a scalar type like Solaris's.
#
# Usage:
# Set to any value in the range: 0 <= value <= 2^wordsize
#
# Examples:
# Set to 0 to emulate non recycle-unique behaviour like Linux or *BSD.
# Set to 1 for recycle-unique thread IDs (this is the default).
# Set to some other +ve value to emulate smaller word size types
# (i.e. will wrap sooner).
#
#PTW32_FLAGS	= "-DPTW32_THREAD_ID_REUSE_INCREMENT=0"
