I've committed a change that adds a variable PERL_EXT_CC. Maybe you could give it a try? I've tested it with the following: $ ./configure 'CFLAGS=-Wdeclaration-after-statement -g -O0 -Wunused -Wimplicit-function-declaration -Wreturn-type' '-C' PERL_EXT_CC='cc -static-libgcc' configure: loading cache config.cache configure: error: `PERL_EXT_CC' was not set in the previous run configure: error: in `/home/g/src/texinfo/PROJ_SVN': configure: error: changes in the environment can compromise the build configure: error: run `make distclean' and/or `rm config.cache' and start over Then after "rm config.cache" and trying again, the output includes... libtool: compile: cc -static-libgcc -DHAVE_CONFIG_H -I. -I. -I./lib -I./lib -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DVERSION=\"6.3\" -DXS_VERSION=\"6.3\" -I/usr/lib/perl5/CORE -MT TestXS_la-TestXS.lo -MD -MP -MF .deps/TestXS_la-TestXS.Tpo -c TestXS.c -o TestXS_la-TestXS.o >/dev/null 2>&1 mv -f .deps/TestXS_la-TestXS.Tpo .deps/TestXS_la-TestXS.Plo /bin/sh ./libtool --tag=CC --mode=link cc -static-libgcc -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DVERSION=\"6.3\" -DXS_VERSION=\"6.3\" "-I/usr/lib/perl5/CORE" -no-undefined -L/usr/lib/perl5/CORE -lperl -avoid-version -module -Wl,-E -Wl,-rpath,/usr/lib/perl5/CORE -o TestXS.la -rpath /usr/local/lib/texinfo TestXS_la-TestXS.lo libtool: link: cc -static-libgcc -shared -fPIC -DPIC .libs/TestXS_la-TestXS.o -L/usr/lib/perl5/CORE -lperl -fstack-protector -Wl,-E -Wl,-rpath -Wl,/usr/lib/perl5/CORE -Wl,-soname -Wl,TestXS.so -o .libs/TestXS.so libtool: link: ar cru .libs/TestXS.a TestXS_la-TestXS.o libtool: link: ranlib .libs/TestXS.a libtool: link: ( cd ".libs" && rm -f "TestXS.la" && ln -s "../TestXS.la" "TestXS.la" ) checking ./TestXS.la found ./TestXS.la message from XS module checking whether we can build Perl extension (XS) modules... yes which has the -static-libgcc flag, so this seems to work.
