Re: Bug in __GNU_GETTEXT_SUPPORTED_REVISION macro definition in gettext.m4

[Martin Jacobs]

Hi,

thanks for your explanation.

My system is an SuSE 8.1 based system using

        glibc-2.2.5

Compiler is gcc-3.4.6.B

Gettext 0.17 is compiled and installed with "my" bugfix. With
that I could compile and install coreutils 7.6, bison 2.4,
...

GNU gettext 0.17 is installed. How can I verify that support
of <inttypes.h> formatstring macros?
