1 dnl Process this file with autoconf to produce a configure script.
3 dnl There are two types of comments in this file.
4 dnl Comments that refer to Autoconf macros begin with "dnl", and m4
5 dnl discards them. Other comments begin with "#", and they get copied
6 dnl to the configure script, hopefully making it easier to read.
8 dnl Autoconf 2.13 generates an incomplete config.h.in; see ELinks bug 936.
9 dnl Autoconf 2.61 is installed in the computer that generates our nightly
10 dnl snapshots, so we need to be compatible with that. (Also, some files
11 dnl in Autoconf 2.62 and 2.63 sources are not GPLv2 compatible.)

1505 # regwcomp function of TRE. Therefore put $TRE_LIBS at the

1507 # regfree there before it examines libc. In particular,
1508 # $PERL_LIBS appears to often include "-lc".
1510 # This scheme still risks a crash if ELinks is linked with
1511 # some static library that uses GNU <regex.h> extensions that
1512 # TRE does not implement. For example, the library might call
1513 # re_compile_pattern, which is found in GNU libc, and then
1514 # regfree, which is found in TRE and probably crashes with the
1515 # GNU-initialized regex_t. Ways to avoid such crashes:
1517 # - Change TRE so it defines only tre_... functions and does
1518 # not attempt to override the POSIX names by default.
1520 # - Change ELinks to access TRE only via dlopen and dlsym.
1521 # The problem then is how to find the correct file name.
1522 # There might be libtre.so.4 and libtre.so.5 with different
1523 # ABI. How can this configure script detect which of them
1524 # matches the <tre/regex.h> in the include path?
1526 # - Replace the static library with a shared library. At
1527 # least on GNU/Linux, when the shared library is built, the
1528 # linker should note that e.g. regfree is defined in libc
1529 # and has the GLIBC_2.0 version there, and write that
