[PATCH] Fix build in locales with decimal comma

[Miloslav Trmac]

Hi,
the attached patch against current CVS fixes @multitable
@columnfractions (and texinfo build) in locales where the decimal comma
is used, e.g. cs_CZ.UTF-8.

main () carefully keeps LC_NUMERIC set to "C", getdocumenttext ()
currently overrides LC_NUMERIC from the environment.

        * makeinfo/makeinfo.c (getdocumenttext): Correctly save and
        restore the current locale configuration.

Thanks,
        Mirek
