The binary version of gnat 3.03 is also contains the binary distribution
of gcc 2.7.2. They are bundled with the "doconfig" script (modified) to enable
the installation of the binaries on your target machine.

Two issues specific to the Solaris x86 version exist:

1. Generation of dwarf debugging output (native for System V R4 Unix and elf)
is STILL broken under gnat. The gcc compiler can correctly generate dwarf
output, however gnat produces bad output for any strings and causes a
compiler abort. To remedy this the -g switch will generate stabs or dbx
output as was native for BSD and older Sun operating systems. Since this is a
port to the Intel, and the SPARC Solaris currently does this as well, the
support is present. To generate dwarf output simply use -gdwarf (for gcc
only).

2. I have been unable to build a version of gdb that can read the stabs
information that seems to be present in a C or Ada program generated by these
binaries. The delivered adb seems to show symbolic information, but is not
very friendly. I have not been able to test with any of the other Sun
debuggers. The gdb debugger will read the dwarf symbolics generated for C
programs.

If anyone can help to verify the presence/absence of stabs symbolics and or
repair the gdb debugger, (or if you are really ambitious fix the dwarf code
generation) the help would be appreciated.

If you wish to rebuild from source, contact me at [e-mail] and I
will send you a patch file and a header file to enable the stabs output. If
you do not use these, you will have to modify the makefiles to remove
references to the -g flag as the produced binary will fail as it processes
the gnat source. I will post the patch file on NYU shortly as well.

Enjoy!!!
