# DESCRIPTION
#
-# Capture version of C/C++ compiler
+# This macro retrieves the compiler version and returns it in the cache

+# for C++.
+#
+# Version is returned as epoch:major.minor.patchversion
+#
+# Epoch is used in order to have an increasing version number in case of
+# marketing change.
+#
+# Epoch use: * borland compiler use chronologically 0turboc for turboc
+# era,
+#
+# 1borlanc BORLANDC++ before 5, 2cppbuilder for cppbuilder era,
+# 3borlancpp for return of BORLANDC++ (after version 5.5),
+# 4cppbuilder for cppbuilder with year version,
+# and 5xe for XE era.
+#
+# An empty string is returned otherwise.

# SYNOPSIS
#
-# AX_COUNT_CPUS
+# AX_COUNT_CPUS([ACTION-IF-DETECTED],[ACTION-IF-NOT-DETECTED])
#
# DESCRIPTION
#
-# Attempt to count the number of processors present on the machine. If the
-# detection fails, then a value of 1 is assumed.
+# Attempt to count the number of logical processor cores (including
+# virtual and HT cores) currently available to use on the machine and
+# place detected value in CPU_COUNT variable.
#
-# The value is placed in the CPU_COUNT variable.
+# On successful detection, ACTION-IF-DETECTED is executed if present. If
+# the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
+# default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.

#
# NOTE: You are assumed to not only compile your program with these flags,
-# but also link it with them as well. e.g. you should link with
+# but also to link with them as well. For example, you might link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
-# If you are only building threads programs, you may wish to use these
+# If you are only building threaded programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
-# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# Public License for more details.

+# SYNOPSIS
+#
+# AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+# been defined and thus are available for use. This avoids random issues
+# where a macro isn't expanded. Instead the configure script emits a
+# non-fatal:
+#
+# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+# It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+# Here's an example:
+#
+# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

+#
+# DESCRIPTION
+#
+# Switch common compilation flags from temporary variables between two
+# compilation namespace.
+#
+# Compilation flags includes: CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS, LIBS,
+# OBJCFLAGS.
+#
+# By default these flags are restored to a global (empty) namespace, but
+# user could restore from specific NAMESPACE by using
+# AX_RESTORE_FLAGS(NAMESPACE) macro.
+#
+# Typical usage is like:
+#
+# AX_SAVE_FLAGS(beginprogram)
+# CPPFLAGS="-Imypackagespath ${CPPFLAGS}"
+# AX_SWITCH_FLAGS(mypackage,beginprogram)
