Subject: [build] configure: don't abuse AC_CHECK_FILE. Unbreaks the cross-compilation.
X-Git-Tag: release_1-6-1~7
X-Git-Url: https://www.ginac.de/ginac.git//ginac.git?p=ginac.git;a=commitdiff_plain;h=47a0c68f3e0c4af0ee22b3ca4fe0e5df66aa69db

[build] configure: don't abuse AC_CHECK_FILE. Unbreaks the cross-compilation.

Checking for ginsh_parser.h in configure is not a good idea, since it
1) produces a bogus warning during an out of source build,
2) breaks cross-compilation.

Solution: just skip that bogus check (auto* tools do a similar check in
the run-time *for a reason*).
