#   Revision 2.1  2000/05/29 13:53:07  cibrario
#   - Deep revision to support transparent, multi-platform builds
#   - Added multithreading support
#   - New/revised targets: test, doc, clean
#
#   Revision 1.2  1996/06/11  13:03:06  cibrario
#   Added new module chf_top.c
#
#   Revision 1.1  1996/05/29  09:12:10  cibrario
#   Initial revision

# Platform-dependent definitions.  Edit when required, for example to
# add a new platform.
#
# There is a set of definitions per platform; the prefix or the definition
# names is the value returned by a plain 'uname' on that platform.
#
# CC: cc compiler
# TS_CFLAGS: cc flags to enable multithreading
# TS_LOADLIBES: ld flags and additional libraries to enable multithreading
# F_CFLAGS: cc feature test macros
# O_CFLAGS: cc optimization control flags and other, additional flags
#
# Supported platforms:
# OSF1		Digital UNIX v4.0
# SunOS		Solaris v2.6
# Linux		Linux 2.1
#
# In addition, if the first build fails, a second attempt is made
# using the X_CC and X_CFLAGS fallback values.
