These were created by rbdannenberg, in commit 932ca88255a322bff833e3eb4e3931a971aa97d4, but were accidently deleted later in commit bb63fa0d07dad9a9f02b75eda455576e6e8b4da4 (which updated portmidi). I can't say whether they work or not, and even when they were introduced it was stated that they may be wrong. But it's better than not having any automake files at all, and will at least provide a base for them. I didn't add some of the sourcefile changes from the first commit (some were already added to portmidi, and others weren't). Some of them may be needed to get building to work (or, we could update portmidi, if there are any changes upstream). I also didn't add any of the libscorealign changes other than one, since libscorealign already had makefiles (other than the uninstalled one). These configure scripts may be really old; regenerating them is probably a good idea.

# SYNOPSIS
|
|
#
|
|
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Try to find a compiler option that enables most reasonable
|
|
# warnings. This macro is directly derived from VL_PROG_CC_WARNINGS
|
|
# which is split up into two AX_CFLAGS_WARN_ALL and
|
|
# AX_CFLAGS_WARN_ALL_ANSI
|
|
#
|
|
# For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
|
|
# result is added to the shellvar being CFLAGS by default.
|
|
#
|
|
# Currently this macro knows about GCC, Solaris C compiler, Digital
|
|
# Unix C compiler, C for AIX Compiler, HP-UX C compiler, IRIX C
|
|
# compiler, NEC SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos
|
|
# 10.0.0.8) C compiler.
|
|
#
|
|
# - $1 shell-variable-to-add-to : CFLAGS
|
|
# - $2 add-value-if-not-found : nothing
|
|
# - $3 action-if-found : add value to shellvariable
|
|
# - $4 action-if-not-found : nothing

dnl implementation tactics:
|
|
dnl the for-argument contains a list of options. The first part of
|
|
dnl these does only exist to detect the compiler - usually it is
|
|
dnl a global option to enable -ansi or -extrawarnings. All other
|
|
dnl compilers will fail about it. That was needed since a lot of
|
|
dnl compilers will give false positives for some option-syntax
|
|
dnl like -Woption or -Xoption as they think of it is a pass-through
|
|
dnl to later compile stages or something. The "%" is used as a
|
|
dnl delimimiter. A non-option comment can be given after "%%" marks
|
|
dnl which will be shown but not added to the respective C/CXXFLAGS.
