rather than find. This behaves better if ${ALT_GCC} does not specify
a gcc executable.
2) Change to uniform handling of ABI baseline-pairs for NetBSD. There
must be agreement between the Makefile and libstdc++-v3/configure.host;
this change ensures consistency by introducing ABI_BASELINE_PAIR
variable used in both.
3) Bump revision number.
alpha--netbsd1.6.2:
1) Rename the baseline_symbols.txt files that define abi and implement
logic in Makefile that uses these according to architecture and
NetBSD version (1.x versus 2.x)
2) Add several patches that allow code to compile on alpha--netbsd1.6.2
3) Revise Makefile so that libiconv is found under NetBSD 1.6.2
Change for AMD64: The patch incorrectly AMD64 to be identified
as x86_64--netbsdelf when it is identified as x86_64--netbsd.
This effect the building of the Ada front-end on the AMD64 target only.
2) Added include statment for zlib/buildlink3.mk to Makefile to go with
CONFIGURE_ARGS+=--with-system-zlib already there. Thank you
Georg Schwarz <geos@epost.de> for pointing out this ommision.
3) Incorporated logic from gcc3 that determines whether to add
binutils dependency or not.
4) Eliminated hardcoded target of netbsdelf2.0 as a step toward supporting
other architectures.
