Enough users expect the namespace starting with underscore to be safe for symbols. Change our private namespace from __foo__ to __?foo?__. Use %defalias to provide backwards compatiblity (by using %defalias instead of %define, we handle the case properly where the user changes the value.) Add a preprocessor directive: %aliases off ... to disable all smacro aliases and thereby making the namespace clean. Finally, fix infinite recursion when seeing %? or %?? due to paste_tokens(). If we don't paste anything, the expansion is done. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

# Parse the NASM version file and produce appropriate macros
|
|
#
|
|
# The NASM version number is assumed to consist of:
|
|
#
|
|
# <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
|
|
#
|
|
# ... where <tail> is not necessarily numeric, but if it is of the form
|
|
# -<digits> it is assumed to be a snapshot release.
|
|
#
|
|
# This defines the following macros:
|
|
#
|
|
# version.h:
|
|
# NASM_MAJOR_VER
|
|
# NASM_MINOR_VER
|
|
# NASM_SUBMINOR_VER -- this is zero if no subminor
|
|
# NASM_PATCHLEVEL_VER -- this is zero is no patchlevel
|
|
# NASM_SNAPSHOT -- if snapshot
|
|
# NASM_VERSION_ID -- version number encoded
|
|
# NASM_VER -- whole version number as a string
|
|
#
|
|
# version.mac:
|
|
# __?NASM_MAJOR?__

# __?NASM_MINOR?__
