autoconf 2.57: broken config.cache on Solaris

[Matthias Andree]

Hi,

I have strange entries in config.cache with an autoconf-2.57 generated
script on Solaris 8 with Sun WorkShop Pro 6. Bash is installed.

I can provide more information, the project that fails is bogofilter
(GPL) which currently uses autoconf-2.57 and automake-1.7.2. configure
and Makefile.in are built on Linux, the packge is built on Solaris 8
Sparc from a bash. /bin/sh is the Solaris crap shell.

When config.status --recheck is run, I get this message:

checking lex output file root... (cached) lex.yy
checking whether yytext is a pointer... (cached) yes
checking for additional compiler options... (cached)
checking for cos in -lm... (cached) yes
checking how to run the C preprocessor... (cached) $/opt/SUNWspro/bin/cc -E
configure: error: C preprocessor "$/opt/SUNWspro/bin/cc -E" fails sanity check
See `config.log' for more details.
make: *** [config.status] Error 1

Here's an excerpt of config.cache:

ac_cv_path_install=${ac_cv_path_install=$'/usr/local/bin/install -c'}
ac_cv_prog_AWK=${ac_cv_prog_AWK=nawk}
ac_cv_prog_CPP=${ac_cv_prog_CPP=$'/opt/SUNWspro/bin/cc -E'}
ac_cv_prog_LEX=${ac_cv_prog_LEX=flex}
ac_cv_prog_ac_ct_CC=${ac_cv_prog_ac_ct_CC=/opt/SUNWspro/bin/cc}
ac_cv_prog_ac_ct_RANLIB=${ac_cv_prog_ac_ct_RANLIB=ranlib}
ac_cv_prog_cc_g=${ac_cv_prog_cc_g=yes}
ac_cv_prog_cc_stdc=${ac_cv_prog_cc_stdc=}
ac_cv_prog_egrep=${ac_cv_prog_egrep=$'grep -E'}
ac_cv_prog_gcc_flags=${ac_cv_prog_gcc_flags=}
ac_cv_prog_lex_root=${ac_cv_prog_lex_root=lex.yy}
ac_cv_prog_lex_yytext_pointer=${ac_cv_prog_lex_yytext_pointer=yes}
ac_cv_prog_make_make_set=${ac_cv_prog_make_make_set=yes}
ac_cv_type__Bool=${ac_cv_type__Bool=no}

Please send directions if you need more information.
