This RFE is for two related issues. I'll call it an RFE rather
than attempt to argue it is a Bug (by omission or inconsistent
behavior).
1: Typing "gcc -v" will print the 'specs info', 'HBT', 'how gcc was
"./configured"', 'the thread model' and 'version / revision'. When
you actually compile a program using the "-v" option gcc will print
out some additional info that may be useful to include with the
more trivial "gcc -v" command.
2: When you actually compile a program using the "-v" option gcc
prints out info about gmp and mpfr but none about cloog , ppl and
pwl.
In the past 'libgmp.so' and 'libmpfr.so' were optional in _some_
configurations, and were tested for during configuration to enable
or disable features. It is my understanding that these libraries
are now mandatory and omission of them will cause configuration
failure.
At present 'libppl.so', 'libpwl.so', and 'libcloog.so' are optional
and are tested for during configuration to enable or disable features.
Are the 'libppl.so', 'libpwl.so', and 'libcloog.so' libraries worthy
of enough "status" to print their versions alongside gmp and mpfr ?
It is also a minor issue that there is some leading whitespace.
Here is an example of "gcc -v" as it currently is (depending upon your
configuration and platform):
# gcc -v
