The following bug has been logged on the website:
Bug reference: 6759
Logged by: jez wain
Email address: jez(dot)wain(at)bull(dot)net
PostgreSQL version: 9.1.4
Operating system: AIX 7.1
Description:
The configure script (near line 3247) detects the compiler version with
--version, -v, and -V
IBM's xlc compiler uses "-qversion" flag to display its version.
This produces:
bash-4.2$ xlc -qversion
IBM XL C/C++ for AIX, V11.1 (5724-X13)
Version: 11.01.0000.0000
If you require additional information, there is a verbose switch,
-qversion=verbose, which produces:
bash-4.2$ xlc -qversion=verbose
IBM XL C/C++ for AIX, V11.1 (5724-X13)
Version: 11.01.0000.0000
Driver Version: 11.01(C/C++) Level: 100304
C Front End Version: 11.00(C/C++) Level: 100301
High-Level Optimizer Version: 11.01(C/C++) and 13.01(Fortran) Level: 100301
Low-Level Optimizer Version: 11.01(C/C++) and 13.01(Fortran) Level: 100304
bash-4.2$
When faced with a flag it doesn't recognize, xlc prints the man page. Thus
the --version, -v, -V tests result in a particularly large config.log file
